A quick update on the the follow-up Yoshino video: it's taking longer to pull together than I thought. It's very clear that the Yoshino battery isn't an "all solid state battery," but I've gone down a rabbit hole of "but what is it?" It's been a fascinating and interesting journey going down this path (no, it's not your standard lithium ion battery as some are saying). I've been talking to experts in the field (like the CTO of QuantumScape and others about solid state in general), working with TechInsights to dig further into some gaps in their initial Yoshino testing, getting additional information from Yoshino itself, as well as working with a fellow TH-camr and friend that has access to university lab to do his own Yoshino analysis. The video is 100% happening, but the investigation keeps revealing new interesting layers to the discussion. Stay tuned.
@@dragoniv He's already addressed the other videos. I'll watch his next video on this because it seems there's some supposed basis for the claim, however flimsy.
@@mike74h Yep, I'll be watching too. I actually bought one of these, and my interactions with the firm confirmed my suspicions that this was a scammy outfit. Didn't take long to figure out they were a Chinese firm misrepresenting themselves as a US firm.
th-cam.com/video/z8sVbwitrB0/w-d-xo.htmlsi=vIfTCOGSgon1wF8M Every second video (figuratively) on this channel is misinformation, idk how he gets away with this for so long
I’m still dubious of many of these tear down videos. There’s still a bunch of misunderstanding around how to verify the solid state claims. There’s more to it than simply sticking a drill through it. Hoping I can bring a lot more detail with the tear downs I’m pulling together. No matter what comes out of it, should be super interesting.
@@UndecidedMF There is definitely more to it then just sticking the drill through. The problem is - company claims that there is no flammable material in the battery.
It is a LIE ! Reviewer took it apart and they are Lithium Batteries caught on Fire bigtb1717 Yoshino Solid State Battery Power Station, Test and Teardown!
I scrolled down here to say the same. Good job! Retractions are so hard to present amidst the flurry of emotions, speculation, debate, and trolling. I very nearly ordered one of these from Amazon after your last video. Thankfully, I also would have seen this correction weeks before my return window expired. And it's still possibly an excellent product worth keeping, but I can appreciate that it takes a while to fully assess bleeding edge tech like this.
Matt, I'm glad you made this update video. Thanks for taking the time. I did a teardown on my channel a couple days ago. A lot of folks in my comments were calling you out and I think coming here and calling you out in your comments as well. Just know it wasn't my intention. Admittedly, your video was part of my inspiration, but not as some sort of critique or anything, I just had some suspicions and wanted to look into it myself. Another gentleman, @johnnysweekends also did a teardown, which was posted earlier today. Cheers!
I watched your video yesterday. Thank you for confirming what I suspected about Yoshino. We need more people like you who don't trust the marketing and actually test stuff.
ITs cut throat world man. anyways. He never addressed the part number being "lithium ion " battery. All i heard was blah blah in his video. That should have gave him pause in the first place. Basic checking first. No lab needed, just eyes and a few words and a few screwdrivers. Hes a big boy. Hopefully he will survive this, but professionally he is still in the nile and wasting a lot of peoples time and money.
Pretty easy to call him out, a majority of videos are like this, just some scammy product in the name of being green, with no real science or no real product
Your video was great and you're not responsible for other people's actions. You actually researched before making claims. Matt, on the other hand... i'm not sure you could even call this a "retraction". He hasn't addressed anything you've pointed out in your video.
Thanks @bigtb1717 . I also appreciated your video very much, and would like to emphasize that you are a credit to the world of ethical reviews. As attractive as the prospect of a tech review channel starring Community's Dean Pelton seems, it was clearly not meant to be.
"Try our vegan burger!" "Oh wow this tastes just like beef!" "The patty is all beef!" "Wait this is beef?! You said it is vegan!" "The pickles are completely vegan."
@@TheKillerman3333 Interestingly, even that wouldn't be considered vegan, depending on the vegan definition. Because the cow couldn't consent to being consumed by humans prior to death, eating its corpse could still be non-vegan. I am not saying that this is even worth talking about (death by natural causes is vegan imo), but some vegans can be nitpicking like that LMAO
@@NothingXemnas i believe you are correct, they can be very nit picky. There was a movie about a guy who had to fight his girlfriend's seven evil exes. One of them was a vegan.
I think every electronic engineer that watched your original video was scratching their head as you described this Power station and your testing results. Everything was completely below expectations, but you were somehow thoroughly convinced it contained Solid State batteries. There were only two things that made me move on and not comment at the time. The first was that you kept the illusion going that this was a Japanese Company and did not declare from the get go that this was a Chinese company. There would have been all sorts of instant Red Flags going off in my head had you stated this was a Chinese company. The second thing was that I actually believed that you had done your Homework. Did you not notice that in all of Yoshino's TH-cam advertisements for this product that they never state that it uses Solid State Batteries? They say it's a Solid State Power Station! This is a true statement, so they are pretty much off the hook. I know Amazon was out of stock of this product within a day after your fist video. How many people bought this Power Station based on trusting your info?
Lots of respect for updating this video Matt! I saw videos tearing it down afterwards and was very surprised and felt mislead. I was about to pull the trigger on this product. Glad I didn't! But again, props for updating your audience and being forthcoming on the whoopsies.
Yeah, when this all came to light I couldn't leave it up without comment. I don't want to do wrong by any of you. Can you share the video tear downs you found? I'm really looking forward to seeing more details on what we find as we dig in ourselves.
Just sent the link in my previous comment. The chemistry wasn't the only surprising thing about this product. Seems the inverter being used in the battery is not that great in comparison to other options in the market.
There is no such thing as a solid state battery. It's literally just using off the shelf lithium batteries that have been sold for over 15 years. Just clickbait bs.
@@TexasStormChaser Wrong! There are Solid State Batteries out there. The problem has been making them to scale and making sure they are reliable for thousands of cycles and at least 10 years.
They are using standard li-polymer cells, while some others use LFP. Li-polymer is lighter, but lasts much less cycles, so the product will die real quick, like all power banks.
Yeah there's tons of these lol. There are currently zero large volume solid state batteries right now. There's tons of falsely advertised units. I caught one on fire on my channel a year ago. You should open every unit you review. Theres tons of garbage out there.
Frankly, I'm disappointed you didn't employ more skepticism. Feels like you *wanted* this to herald the beginning of Solid State Batteries, that you disregarded the probability of this being only deceptive marketing.
@@InspectorGadget2014 you wont be missed bud, comments that got deleted likely were hateful, including yours, which is unsurprising to see you still stew over it and unsub because of it.
At the 14:23 mark you claim that Yoshino's battery "is safer too" when showing the comparison chart with LFP batteries. How did you come to the conclusion of this battery being "safer"? I just watched another person's video where they punctured the cells in Yoshino's battery and those cells started to rapidly smoke, exactly in a way the other types of LFP batteries would do. So how is this "safer"? Serious question.
Matt, just like I mentioned on your first video: Regardless whether this is solid state or not, the higher energy density comes from the fact this uses NMC cells and not LFP like the powerbanks you compare it to... NMC cells have an average energy density of 250Wh/kg, while LFP sits around 175Wh/kg.
Unlisting and linking the original is great. You get the full value plus the update's value in this video, and the unlisted video now won't show up in the algorithm and deceive people, while it's still available for the sceptics to go through, but they have to go through this video first so they better come with points that aren't already raised. I'm looking forward to the part 2, and I think this should be the golden standard of 'partially retracting a video which still has value'. Unlist the original. Update part 1 and link to the original, then work on a part 2. It leaves no uncertainty during the investigation.
👍 It's taking a while to pull part 2 together and I couldn't leave the original up getting served via the algorithm. Glad to hear you think this was a decent approach for transparency and handling it.
@@UndecidedMF Let's hope this video does even better than the original. Authentic, nuanced clarifications, retractions, corrections, and well cited fact checking really need to be amplified over other social media content. This is much harder to measure than simple engagement-based algorithms (primarily outrage and outrageousness), but given the existential threat that social media represents for literally every aspect of society I can only remain hopeful. Perhaps LLM AI models will reign in the accelerated pace our echo chambers amplify the worst of human nature and instead bring out the best. Thanks Matt for risking the loss of income for this retraction.
Props I guess for taking down the original, but it's really the bare minimum required here. You presented a no-name manufacturer's marketing as factual proof and didn't do the most basic investigation to verify it. The little research you did do gave no indication at all that these are anything other than regular Li-Ion batteries with liquid electrolytes. Bring more skepticism in the future. Do the work. Don't buy into marketing BS.
@@clevernduruza8624 What are you watching they don't explode, when punctured they enter thermal runaway and burst into flames this applies to all lithium ion cells
Whaaa whaaaa my battery doesn't like getting shot with arrows whaaa whaaaa. There are way to many dum dum's on the internet, no correction there are way to many right wing filth on the internet who just don't like it that fossil fuels are bad for the environment and who cry their eyes out each time someone mentions climate change. So they have to hate on anything related to 'green technology' just to feel like they are helping fight 'climate nonsense'
If you want a "light and dense" camping battery, the way to go is a 24V LFP. Many if not most things that can plug into a 12V cigarette lighter port are now designed to also work at 24V. 24V carries the power out more efficiently than 12V on the same wiring. Then you leave the power inverter at home. Say you hook up my portable fridge. AC power is measured at 73W when running. DC 24V seems to be ~60W. Average DC draw is ~30W on 24V as in I calculate this number against the Wh rating of the battery to get total estimated run time on battery. So DC you cut out the conversion loss of say 10% and parasitic draw of say 5W to go from 24V DC to AC, you dump the inverter overboard all together, and you get rid of the conversation loss in the fridge from 115V AC back to 24V DC of ~20%. You may lose on average ~40% of your power between conversion loses and parasitic draw of the inverter, which is now all dumped overboard. Now say it just goes straight 24V DC from the battery to the fridge. There is a 0.5V drop from the battery to the fridge while running over the long DC cable that comes with the fridge. With 12V, you have a 1V drop and twice the current. So you go from a ~2% transmission loss to an 8% transmission loss going from 24V to 12V. So AC conversion ~40% loss. 12V is ~8% loss to go from battery to fridge. With 24V it is a ~2% loss to go from battery to fridge. 24V DC battery is the winner here. Now what else do you want to power on your camping trip? 1. USB - USB chargers are available that very efficiently take 24V power and buck it down to your device voltage. For PD, the output voltage is typically 20V, so a DC-DC buck conversation from say 26V of an LFP battery to 20V is about the most efficient thing you can possibly do. Nearly 100% efficient. So again a 24V battery wins. 2. Dedicated laptop charger - Say you have a laptop with a dedicated power plug, not USB-C PD. A standard Dell power supply for example is 19.5V. Again going from ~26V of an LFP battery to 19.5V through a simple buck conversion on a buck-boost converter is about the most efficient thing you can possibly do. Nearly 100% efficient. They make a variety of these and ones that are "universal", so pretty much any laptop can be powered this way even if you don't do USB-C PD charging or it kind of sucks on your particular laptop model. 3. Starlink Mini - This can take a 100W USB-C PD power supply. Again 20V. So a 24V LFP battery to do this primarily doing a buck conversion (maybe use a voltage stabilizer) is the most efficient thing you can do. 4, Cell booster - They make these that can plug into a cigarette lighter port. I am sure you can find one with a power supply rated for a 24V LFP battery. 5. Cooking - Use a propane stove. Job done. No electricity needed. Anyways, bringing an electric hot plate or microwave oven is a lot more crap to lug around. Just bring a propane stove and call it a day. And you know for hot coffee, you could just boil hot water on the propane stove. This process does work without your electric espresso machine. 6. Lighting - USB charged lights. No AC power needed. Why would you fuss with a propane or white gas lantern? I mean an LED light you just press the button and it turns on and off. And why would you bring an AC lamp or something with you? You are camping here, right? Really, what are you bringing an AC inverter on a camping trip for? Just dump the inverter overboard and then you have "light and dense". Certainly lighter and denser than any of these portable power stations.
Hey now... Check out the Wacaco Picopresso....portable espresso machine. All you need is the boiled water. There's also the Outin which you can easily charge. Option to use with boiled water significantly increases the unit's battery life if it doesn't have to heat the water as well. Then there's the Aeropress. While not espresso, I'm just adding that there's kinda no excuse to not have excellent coffee anywhere... Subminimal Nanofoamer if you need foamed milk. :p Didn't expect to see VSWR stuff.
Honestly I've learned to never take your videos serious. Sent it over to a friend and we both were instantly skeptical. You really have to spend more time not giving crack pot science and scam companies a voice.
Great update. I appreciate your integrity and desire to get the facts right. It's part of why I subscribed to this channel. Also, I have to say you have great production and audio consistency. Hearing your voice some time after the original recording back to back, I couldn't tell they were recorded at different times. Many times, ADR after the original recording can sound wonky. Good all around! Keep doing what you're doing.
Watched this update, it's good you published a qualifier but you really need some more reflection on why no deeper thought was done for the original video. Own your mistakes. Many of the people who watched the video and perhaps bought the product are likely never going to see the updated video. This is especially important because of the potentially inaccurate safety claims the company makes, which you don't even note in this update.
My biggest problem isn't that there might have been small mistakes in the video. My biggest problem is that we keep constantly, repeatedly, and clearly, hearing from you, that these new breakthrough battery technologies from the future that will revolutionize everything... are 2x or 3x battery density or charge/discharge speed. A 20% (or whatever) increase isn't revolutionary or a breakthrough. It's marginal improvements over existing products, and that's progress, sure. But it's just not what was promised by these companies and especially not by all your previous videos. When we ask to see these revolutionary breakthroughs from the future, we want a 2x 3x 4x battery capacity on the same weight, or a battery with the same capacity that's 50%, 40%, 30% the weight of their competitors. That's what you keep alluding to, and we're still waiting for.
First off, I think this sounds suspiciously like a huge ad. That's very disappointing. Secondly, you can't expect a first iteration product of anything to perform as well as the most mature and final iterations of the last gen product. THat's not how things work. First iteration stuff is sometimes even just on par with the previous gen products. If you compare the larger battery pack, there is substantial weight savings. Now that mass production is in full swing, there will be rapid advancements. Patience is not a virtue that people seem to even pretend to have anymore. Regardless, this still seems like a huge ad and is very disappointing. I know he said he has no association, but something seems fishy.
I mean, the thing is we're not going to hit that sort of thing instantly. Like, battery tech multiple times better than it was 10 years ago, and orders of magnitude better 20. Since a lot of the individual components of a battery could be optimized or replaced, you're only going to see very slightly improvements year over years, that add up to batteries being that much better. But if you compare batteries that came out close together, they're going to be close in performance.
Ok sure but how many times have we heard outlandish claims and the only barrier to production was "scaling up"? I don't want a 10% increase in capacity - you can probably get this by offsetting a battery with lighter materials around it. I'm still waiting for the dozen 2x 3x capacity that we're waiting to come out of factories. Until then, I don't see the point. It's certainly not "revolutionary" in any way.
@@eslachance Chill bro. Not sure how old you are but remember first gen Li-ion batteries? They were markedly better but nowhere near as good as they are now. The tech will mature. If you don't want to "constantly" hear about emerging tech, then stop reading about it. Science takes a long time to become a product you can buy. That's how it's always been.
@@roots4x I'm chill, man. I'm not saying improvements are bad. I'm just relating that Matt is really quick on the "revolution" and "future", and has been taking about these batteries for years, and like I said, has clearly stated throughout these years that the biggest thing preventing commercial products was mass production and costs. These Yoshino packs aren't much better, and they're not much more expensive, and my only point is that they are only a marginal improvement. It's an opinion, man, and I'm expressing it. If you don't like reading contrary opinions, it's also within your power not to read them.
You need to do better vetting of products before rambling on about them, taking companies words on things, and parroting them. You should be ashamed! Not praised for making corrections after the fact.
Great job on actually responding to comments. Not just with adding to the forum, but going as far as to re-release video content with markups. very few content creators do this, so it is highly appreciated.
I saw this coming from a mile away when I saw the original video. I was waiting for you to tear the thing apart throughout the video. The fact that you keep saying its solid state battery without ever confirming it yourself was a major oversight. At least you're owning up to your mistake. Looking forward to the investigation video.
Did anyone else notice the lack of covers for the outlets/inputs? This should be a show stopper for anyone wanting to use this outside. Just don't do it.
I find the nitpicking about the definition of 'it's here now' really tiring. Yes, of course you can argue that a product that has been shipped to a few beta testers is not 'yet here'. However, the product you show is readily available for everyone to buy, with the only limitation being the production capacity of Yoshino. If it has been sold 3 times or 3 million times shouldn't matter. Ferrari's are not the dominant cars on the roads, but I've never heard someone say Ferrari's 'aren't here yet'.
Another youtuber also disassembled the power station. The model number of the batteries are easily seen; a quick google search of the model number brings up sites selling them as regular old lithium ion batteries.
I’m glad to hear that he delisted the old video. While caveating the original claims is a good start, I am still disappointed that he focuses only on whether the company made misleading claims, but does not take any responsibility for his role in spreading them. This is claimed to be a first-to-market product from an unknown company that registered itself only two years ago. Claims made by an established brand with a reputation should invite a healthy scrutiny, but claims from a new brand with no reputation-let alone one with revolutionary claims-should be met with much greater scrutiny. When a content creator gains a significant following, I believe there is a responsibility to prevent the spread of misinformation and do at least some due diligence before presenting products that may be seen by millions. This doesn’t necessarily mean that he should’ve torn down and tested the product himself, but it should at a bare minimum include researching if claims have been independently vetted and verified, and if they have not, to simply present them as unverified claims. I hope this experience informs the way in which he presents technology in the future, and in the future investigation video he is willing to be transparent and acknowledge his mistake.
There is absolutely no chance that a no-name NMC-based battery is going to last 4000 cycles or anywhere close to as long its LFP counterparts, regardless of its (probably not) solid-state electrolyte. My guess is that this battery is a semi-solid-state battery, which doesn't have the core benefits of the all-solid-state batteries we keep hearing about. Even if they are telling the truth about the battery chemistry, they are 100% lying about the longevity of the product, which should take away any credibility they have for the rest of the spec sheet.
I told you so. I and many others warned against taking the company's word at face value for claims that sound too good to be true and as the first major breakthrough. Especially when their product doesn't have the cell spec sheets to go with it and the specs of the finished unit is worse than other units using conventional cells. It was also a company with zero track record. Now with other youtubers doing digging, this is yet another Chinese company (using a California warehouse address) selling a product with a cell with liquid electrolytes/solvents (so not solid state). I hope next time before doing a similar review, you will either do your own teardown or wait for others to do a teardown to confirm what cells are actually in it. It's ok to make a mistake if you learn from it.
So happy to see actuall followups and corrections. this is what makes reports, channels, etc actually good and reliable. No one is perfect but most newsoutlets and youtubers don't follow up at all, let alone when they know there is important information they should be adding. Well done thank you and the team for all the hard work
thank you for posting chapters for the future matt updates... I watched the original and didn't want to look for those updates... and thanks for the transparency on these updates... I look forward to the follow up info!!
No matter what its super sketchy that a new company with no other products pops up out of no where, and claims to have the only solid state battery on the market for months and no other major manufacturers even announces any competition. Yeti, Anker, or Jackery would have something at least announced by now. The fact this has sketchy things popping up about it doesn't surprise me, and I will never trust a company that even partially lied about their first product. This was their introduction and they failed.
The one thing about all of these manufacturers that drives me crazy is how they market battery power systems as "generators". I would rather buy from a company that knows the difference, and doesn't assume that I'm stupid.
I am SO HAPPY you did a follow up on Yoshino products. I will be purchasing a battery backup solution soon and was leaning towards Yoshino. But, I will be happy to wait before I drop thousands of my dollars on false claims. Side note: I tried to contact Yoshino on getting their B4000 at the discounted Amazon Deal price ($2,699) and never heard back from them... Sigh...
Thank you Matt for staying true to the facts and updating all of us, rather than just moving on to the next thing and ignoring any issues that were brought up. I'm glad there's creators like you who take responsibility and pride in their work to get things right and set the record straight.
Thank you for making this kind of correction. You did great breakdown of power/weight in 10 min mark. It was transparent and well explained, that you mean whole unit you are using, not battery cell density only and is what is needed to make buyer decision.
3:50 The first red flag for me was how long it takes to charge. SS batteries should charge considerably faster; it is one of their primary advantages. Right now there seems to be little reason to spend a premium for nearly identical performance to other brands on the market. And if the company is being dishonest or at least dodgy about how they classify their tech, I don't trust their claims for cycle count and longevity. Thanks for the update. I'm passing on this brand
th-cam.com/video/z8sVbwitrB0/w-d-xo.htmlsi=YWfNAnnX4KNwZZbq clearly not solid state for multiple reasons. The individual cells inside of this has a part number that leads directly to a tech sheet from a standard lithium ion battery. Furthermore directly from their website a breakdown of the build of the cell clearly shows organic solvents not inorganic solvents. And in this video he punctures the cell and it ignites on fire..
Excellent followup, I was very excited to start seeing SS available to purchase soon™, but it seems we still have to wait for the tech to be more mature and more information is generally available at a consumer level to decide what is SS and what is not. My only suggestion for your next video would be to measure and test your units W/h and compare with the given spec (heck adding at least one of the lithium batteries would be good). We take at face value what these companies tell us about capacity, but reassurance for consumers is always good.
Thanks Matt for doing this UPDATE, and providing transparency into what is known, for the Undecided community. It would be nice to have more clarification on what the battery industry considers "solid state". My understanding that solid state is just a reference to the electrolyte used in manufacturing the cells, which is a gel, or a dry paste. This is said to improve assembly efficiency in manufacturing. If there is not an industry conscientious, that would also be good info. As far as cell energy storage capacity, it is my understanding it is determined by the storage capacity of the anode and cathode materials. Storage capacity of anode and cathode need to be similar, otherwise the higher capacity material is limited by the lower capacity material. Matt, it would be helpful to touch on how all 3 components (anode, cathode and electrolyte) effect cell capacity. For example, if a dry paste electrolyte takes up less cell volume, then the surface area of a given volume cell can have more cell layers, thus more surface area. (ie: increase capacity). The other area of interest is "solid state" cells are suppose to have much higher cycle life (full charge/discharge cycle counts), as the thick gel, or solid paste type of electrolyte is suppose to stop hair-like dendrites from growing between the anode and cathode. This is harder to verify, as it requires putting multiple cells through an endurance test to measure how cell capacity decreases over time, under different temperature conditions. (cold, near room temperature, and warm)
Awesome comment and suggestions to cover in the follow-up. You and I are thinking along the same lines. I do think there's a big issue between what is technically a solid state battery vs. perceptions, so I'm going to hit on that in the video with some experts to chime in on that (trying to get that lined up now). Once we have that baseline established we can explain why Yoshino is or isn't a solid state battery. As frustrated as I am at myself for ending up in this situation, I'm also loving it. It's a great learning opportunity and I can't wait to share what comes out of this.
This the best attitude .. "It's a great learning opportunity." The technology is just making its way from the lab into mass production, so there is a limited amount of good information. Really appreciate you taking the extra effort to better understand and share to educate a larger audience.
Yoshino’s power stations all use batteries with an Inorganic Polymer Composite electrolyte that is recognized by the scientific community as “solid-state”. Yoshino is the only company offering commercially available power stations that fit this description.
One major oversight Matt- You referenced operating temperature ranges, but not CHARGING temperature ranges. This is critical information for someone looking to set up in an unheated shed, barn, garage etc., where charging below 32 F would destroy most Lithium batteries.
This is my main problem right now " Some residual binding fluid, composing less than 5-10% of the total battery’s volume, remains as a result of the manufacturing process." I would like to know what this residual binding fluid is and if it is in any way bad and could cause the battery to catch on fire.
Thank you so much for the update, I'm looking forward to the things you're still working on updating. Also, I hope the TH-cam algorithm is nicer to you for this update. Or to put it another way, please forgive me for not watching the full video and clicking through to the update segments. Hopefully this comment will help offset my lack of view time =).
What was the point of an update without the testing results? Just wait until you actually HAVE all the answers and caveats rather than making a halfway-fixed video.
Sorry to say, Your video Sounded more like Advertising this battery rather than really telling us about the question that you highlighted in the video title. Sorry but one dislike from my side.
It didn't pass the penetration test, it is not solid state - period. This update isn't updated enough to truly report about this battery. The ground news sponsorship is hilarious when talking about bias.
Penetration testing isn't how you determine solid state or not (solid state batteries can still catch fire ... just far less likely). As I stated in the video, I'm digging deeper into this trying to figure out why Yoshino is even trying to claim solid state. My investigation is almost complete, so the follow-up shouldn't be too much longer. I've been talking to a lot of experts, getting additional lab testing done, etc. So if you want throw shade about being biased, yeah ... I'm trying not to be biased in my investigation and being extra thorough to cover all the bases. Far better than doing unscientific penetration testing in my driveway and calling it done.
@@UndecidedMFBeing thorough and covering all bases should have been done before making this video claiming Yoshino has solid state battery packs. I generally like your channel but it is sad to see someone such as yourself do absolutely zero research before promoting a product like this. People trust you man and this is very disappointing. Hopefully you can recover from lying to your viewers as I like this channel. But it's going to be very hard for myself and others to take you seriously from now on.
@@pnwlifevlog If you’re referring to my statement that solid state batteries can still burn, they can … just far less likely to. Polymers can burn, so a polymer solid state battery can still burn. I’ve spoken to multiple people in battery research and development about that.
@@cameronmacdonald6525 if I was lying, then you mean I knew this to be untrue and still published the video to deliberately deceive people. I did not. I should have dug deeper, yes, which is why I published the correction and am doing a crazy deep, deep dive investigation now. This isn’t as clear cut/simple as many think it is (ie. “is Yoshino solid state or not” … it’s actually a fascinating broader issue in the industry), but regardless this was a learning lesson for me. Nobody is perfect and I can only admit when I missed the mark and do better next time.
I had a hunch when the original video was posted that we were gonna come to find that everything wasn't what it seemed. Looking forward to the full report. I honestly hope that actually is a solid state battery.
Just a piece of info for everyone as I use and test these products regularly, So do you know how many classes of lithium batteries there are? Did you know LFP falls under a class of lithium ion batteries? Did you read every individual ingredient in the MSDS sheet to categorize what percent makes it NMC or solid state? Are you speculating just because it says lithium ion? If you are a professional I won’t doubt you, but since there are several classes or lithium ion batteries I would rather have the rest of the facts verses just an assumption. Hence a couple of us are trying to get the correct info before we come to a conclusion. To many have already concluded with no factual material yet except for what we have seen. But let’s wait to hear from the experts. Hopefully in a few days or next week I’ll have a follow up video and maybe others will as well. Battery make up and chemistry is what’s important. Not the class it falls under.
Wrong! There are a set of physical and minimum electrical Standards that have been presented by the companies working on SS batteries. This Battery fails on every promised feature. Also did you watch the TH-cam Video by "bigtb1717"? He pulled the Powerstation apart and showed us the Labels on the pouch Cells. They are standard Li-ion Pouch cells. I don't know what more Matts "Team" are going to uncover since the markings are right on the cells. They also Catch on Fire in a nice spectacular way just like a typical Ni-Ion cells.
Did you not watch both of my tear down videos ? Are you a battery expert ? Just because he shot a arrow and decimated a battery pouch which he actually needed two arrows, I did several puncture test with nails, and no fire or explosion happened with my pouch cell from my Yoshino unit. I did a full dissection of the battery. Battery tech and voltages change with tech. So unless you know a 100% for sure, or again are you coming to a short conclusion? Do you know what makes the exact difference from a NMc batt and a solid state? I know these pouch cells absolutely do not react like a NMC battery. And it’s definitely not LFP
The real question one need to ask is, based on the product, and most importantly how it is used, do you really care if it is solid state or not AS LONG AS provides the needed service. Regrettably the click bate videos that push the "solid state" idea as some kind of panacea have created this "solid state" mania and such should take responsibility, but regrettably that will not happen as that will damage their cool tech image, which is the bread and butter of the cool tech click bate industry.
I think it originally said it was a hybrid solid state, and my guess on that was that it just used less liquid electrolytes, but i was still hopeful it would be different, which is why i didnt say anything negative on the original video. My problem has been that it still uses nickle and cobalt which until we have testing on this differetn formulation, we'll have to assume the similar 500-1000 cycle rating as other NMC batteries, as opposed to the 2000-6000 cycles of LiFePO4. Now that others have torn them apart, it doesnt look like it has that much less electrolyte either but I'd still like to see more testing.
This update was the way to go. Kudos to you, Matt. On a side note, I was wondering the other day what happened with space tourism. I guess millionaires keep getting in orbit, but it seems to have completely disappeared from the news. As a regular bloke who hopes to still be healthy enough by the time I'd be able to afford a zero-g weekend in my old age, it'd be interesting to see an update video on the subject.
For orbital (ie., longer than 5 minutes!) space tourism, the only options right now for "a zero-g weekend" are Dragon & Soyuz. New Shepard & Virgin Galactic are simply 10 minute hops total, & basically straight up & straight down again, barely touching the Karman line. (or not even touching for Virgin Galactic) Dragon & Soyuz will set you back US$50-90 Million a seat, so not really an option for even remotely close to a regular person. Sierra Nevada's Dream Chaser crew version will also be in this category when it comes online probably late in the decade (for crew - cargo version is due for first launch in the coming months). SpaceX's Starship is the only thing in development that has any hope of getting anywhere near "regular person" holiday price range. It's another economy of scale thing - most will be very surprised how big it is when they see the eventual cabin tour videos. (more volume than an ENTIRE 747 pressurised fuselage volume!) They MAY eventually get ticket prices for short flights down to the low 6 figure range - cheaper than both New Shepard & Virgin Galactic, but for a couple of days fully orbital. Nothing else I'm aware of in development comes remotely close to Starship's longer term price possibilities. You might want to follow the Polaris Program, lead by Jared Isaacman, partnering with SpaceX. First flight (on Dragon) is coming up soon (currently late this month [26 August 2024]), called "Polaris Dawn." They will be doing the very first commercial spacewalk. Flight 3 is aiming to be the very first Starship only crewed mission - launch to landing - though that will likely be a couple of years away. After Polaris flight 3 is when the fun really begins for space tourism! (& the commercial space future in general, that all of us scifi fans have been waiting decades for)
@@drillerdev4624 No probs, & yup, I've been following SpaceX since the Falcon 1 days (still kicking myself for not going outside 1 hour after the first Falcon 9 launch - would have been a specatular sight [large glowing spiral plume in the pre-dawn sky], & even made the news). SpaceX has been the first company in my near 5 decades that has the promise (& leadership drive & ambition) to begin delivering the scifi future we've been promised for decades since Apollo times. Their success has also paved the way for several other companies with great prospects too - Rocket Lab, Firefly, Relativity, Stoke, Astra among others. (Still waiting on Blue Origin to actually send a gram to orbit before I get excited about them again!)
Great news. Not that you were possibly wrong or deceived, but that you made corrections and doing a deeper investigation. If only all the reporters did such a job truth would not be so hard to come by these days.
thanks for the update. I love it when people do updates when things change myself when looking for a battery I am looking for something that can power my computers for an hr or two (3 about 3 year old full sized computers) I already have something backups for my medical equipment that will work for 3 days+ but that is also a 5 year old system that still works fine.
Two important items related to solid state promises of the past that were left out: How does the cycle life compare to LFP including tolerance to deep depth of discharge? How does peak power compare as well for LFP of the same size?
The battery cells have text and a QR code that identifies them as LIPO batteries. The company's own web site has a graphic that shows the batteries are not solid state. The other TH-camrs that did tear downs all concluded that they they are regular old LIPO batteries. They cost as much as other LIPO batteries. They have the same performance and specs. They burst into flames if exposed to air like LIPO batteries. Is any of this conclusive enough for you?
I almost bought this based on your original video. Glad i didnt. While I'm glad you're updating and correcting, hopefully there's a lesson here for someone with your size of platform and the reach/influence you have. With such an outstanding claim like solid state, it was lazy to not do this research and legwork before initial publication. Regardless, you're doing the right thing now and that deserves praise, so thank you.
This has happened so many times for decades. New technology with high potentials around the corner. Companies doing their R&D are timid to go public. Then a company drops news they are selling. Turns out it's a scam! But the company selling the scam (unknown at the time), finally encourages those in R&D, to go public. The hero no one wanted.
Great post Matt. I appreciate the update and look forward to your next post. On the surface it appears the solid state claim is a stretch at best. I’ve heard this product more accurately referred to as a semi solid state or hybrid battery. Either way, introducing your company and product with misleading information is a really bad idea.
👍 I agree with your statement. If it turns out this is a semi/quasi solid state of some kind, it's going against what the public thinks/knows of solid state (that's a problem). I'm keeping an open mind until I see the lab results from my friend.
This is a great way of doing it. The only thing I would say is change the thumbnail to say or indicate some way that it's a re-upload. TH-cam kept recommending it to me and I'm like stop showing me some thing I've already seen. But then I saw the other video so it popped up again I thought well maybe double check. Yeah original video goes unlisted and update the description then new video goes up I think that's the way to do it. As the original video was pretty good apart from the information that needed to change. And I want to support a reupload with good views but need to know that it's a re-upload to click on it.
At the current state of solid-state technology, no mass-produced battery is completely liquid free. Some residual binding fluid, composing less than 5-10% of the total battery’s volume, remains as a result of the manufacturing process.
“Serious issues with how they marketed it.” Yeah. They lied. Thank you for posting the update/retraction. Hopefully any TH-camrs that took a sponsorship from the company will also post retraction/updates. Very curious if any of the noted manufacturers of the packs are also lying.
The most important question for the end consumer is not if the battery is solid state or not. It is the observable and repeated difference in the performance of the system. As compared to what has been historically available in the market. As of this moment, from what I have seen. A real world comparison between Yoshino and others has not yet happened.
On a more positive note, Samsung just started delivering their first round of Solid state batteries to an undisclosed car manufacturer, currently the Samsung battery is at 500Wh/kg at the pack level. Their pilot production line is already up and running, and they expect to be in full mass production by 2026. Do have a look at that one!
Good stuff. You don't just want ion energy density, you want rapid rechargeability to maintain work/time. A muscle ion processes tends to be stronger than a electric motor of the same mass, because it can continuously restore potential, while diffusing energy, therefore ion gradient energy density is a narrow focus, because the goal is work/time. Because you don't need (1 type of energy density) not to just have all the energy density in the form of (ion gradient energy density) considering work/time, because there is a voltage to consider in terms of the appliances being run, it's enough to have faster rechargeability, and chemical potential energy density, rather than high ion gradient potential energy density. Because a battery is not meant to diffuse it's power all at once, therefore high ion energy density potential is irrelevant and not practical, it's a error in measure of a batteries capability, because that's not what batteries job is, rather work/time is a batteries job. There are other energy densities that can be stored. Biological systems have many types of energy density storage, these energy densities are one a type of conveyer belt that resources the ion potential progressively as charge is diffused. It needs to be like a piston, cycle around from potential to release potential to release, where the oxygen and gas in the motor is not a total measure of the potential of the motor, but rather there is a gas tank that is not being considered. It's about the non-frictionless transfer between multiple types of energy density, and the efficiency, and sustainability of tech without pollution or drudging up the sea beds, or slave labor in Africa for rare earth metals, and it's about progressing science and engineering past the community of peers one eyed cyclops mode nonsense.
There are many misconceptions of what “solid-state” actually means. Yoshino adheres to the commonly accepted scientific definition that a solid-state battery is one that uses a solid electrolyte in place of liquid or gel electrolyte found in traditional lithium batteries.
Matt.....one thing I am sure of that I got my B330 for 149 dollars so I got a good deal and I got my B4000 for just over 2600 dollars........I got free shipping on both and paid no taxes.
Thought it was sloppy of you to not actually investigate properly 😕 but glad you are making corrections. Well done on not being irresponsible. P.s they are definitely not solid state batteries, it's still definitely lithium that just uses a polymer electrolyte. It's not solid, it's a gel

A quick update on the the follow-up Yoshino video: it's taking longer to pull together than I thought. It's very clear that the Yoshino battery isn't an "all solid state battery," but I've gone down a rabbit hole of "but what is it?" It's been a fascinating and interesting journey going down this path (no, it's not your standard lithium ion battery as some are saying). I've been talking to experts in the field (like the CTO of QuantumScape and others about solid state in general), working with TechInsights to dig further into some gaps in their initial Yoshino testing, getting additional information from Yoshino itself, as well as working with a fellow TH-camr and friend that has access to university lab to do his own Yoshino analysis. The video is 100% happening, but the investigation keeps revealing new interesting layers to the discussion. Stay tuned.
It takes serious determination to pursue something like this, as I know well from my lab time while earning a BSEE.
I saw a teardown of another model of Yoshino Power Stations, it was all li-ion pouches. This is a scam Chinese firm, plain and simple.
@@dragoniv He's already addressed the other videos. I'll watch his next video on this because it seems there's some supposed basis for the claim, however flimsy.
@@mike74h Yep, I'll be watching too. I actually bought one of these, and my interactions with the firm confirmed my suspicions that this was a scammy outfit. Didn't take long to figure out they were a Chinese firm misrepresenting themselves as a US firm.

Thank you for the update. I was disappointed when I saw another youtuber tear it down and discover it wasn't what it claimed to be.
I’m still dubious of many of these tear down videos. There’s still a bunch of misunderstanding around how to verify the solid state claims. There’s more to it than simply sticking a drill through it. Hoping I can bring a lot more detail with the tear downs I’m pulling together. No matter what comes out of it, should be super interesting.
@@UndecidedMF Good point. I just as much look forward to learning the result as how battery chemistries are properly torn down and studied.
@@UndecidedMF one teardown told that a part numer on cells leads to data sheet of standard lithium cells
@@UndecidedMF There is definitely more to it then just sticking the drill through. The problem is - company claims that there is no flammable material in the battery.
It is a LIE ! Reviewer took it apart and they are Lithium Batteries caught on Fire

Yoshino Solid State Battery Power Station, Test and Teardown!
This is really awesome to see a retraction/correction if there is an issue with a video. Good job, and please continue your hard work!
Thanks, will do!
I got this to be a power source inside the car being charged by a solar panel. It will not charge inside the car it just gets too hot in there.
I scrolled down here to say the same. Good job! Retractions are so hard to present amidst the flurry of emotions, speculation, debate, and trolling. I very nearly ordered one of these from Amazon after your last video. Thankfully, I also would have seen this correction weeks before my return window expired. And it's still possibly an excellent product worth keeping, but I can appreciate that it takes a while to fully assess bleeding edge tech like this.
It's really the bare minimum required here. The original video was awful.
All journalists makes mistakes. Good journalist correct their mistakes and makes it known.
Matt, I'm glad you made this update video. Thanks for taking the time. I did a teardown on my channel a couple days ago. A lot of folks in my comments were calling you out and I think coming here and calling you out in your comments as well. Just know it wasn't my intention. Admittedly, your video was part of my inspiration, but not as some sort of critique or anything, I just had some suspicions and wanted to look into it myself.
Another gentleman, @johnnysweekends also did a teardown, which was posted earlier today. Cheers!
I watched your video yesterday. Thank you for confirming what I suspected about Yoshino. We need more people like you who don't trust the marketing and actually test stuff.
ITs cut throat world man. anyways. He never addressed the part number being "lithium ion " battery. All i heard was blah blah in his video. That should have gave him pause in the first place. Basic checking first. No lab needed, just eyes and a few words and a few screwdrivers. Hes a big boy. Hopefully he will survive this, but professionally he is still in the nile and wasting a lot of peoples time and money.
Pretty easy to call him out, a majority of videos are like this, just some scammy product in the name of being green, with no real science or no real product
Your video was great and you're not responsible for other people's actions.
You actually researched before making claims.
Matt, on the other hand... i'm not sure you could even call this a "retraction".
He hasn't addressed anything you've pointed out in your video.
Thanks @bigtb1717 . I also appreciated your video very much, and would like to emphasize that you are a credit to the world of ethical reviews. As attractive as the prospect of a tech review channel starring Community's Dean Pelton seems, it was clearly not meant to be.

I think every electronic engineer that watched your original video was scratching their head as you described this Power station and your testing results. Everything was completely below expectations, but you were somehow thoroughly convinced it contained Solid State batteries.
There were only two things that made me move on and not comment at the time.
The first was that you kept the illusion going that this was a Japanese Company and did not declare from the get go that this was a Chinese company. There would have been all sorts of instant Red Flags going off in my head had you stated this was a Chinese company.
The second thing was that I actually believed that you had done your Homework.
Did you not notice that in all of Yoshino's TH-cam advertisements for this product that they never state that it uses Solid State Batteries? They say it's a Solid State Power Station! This is a true statement, so they are pretty much off the hook.
I know Amazon was out of stock of this product within a day after your fist video. How many people bought this Power Station based on trusting your info?
Why would a chinese company raise red flags?
You do know what CATL is, where they are from and what products they make right?
Can you cry harder about not trusting CN companies, you might seem even more sub... well below the normal human intellect for sure.
@@LinkesAuge 🤨
Bravo

Lots of respect for updating this video Matt! I saw videos tearing it down afterwards and was very surprised and felt mislead. I was about to pull the trigger on this product. Glad I didn't! But again, props for updating your audience and being forthcoming on the whoopsies.
Yeah, when this all came to light I couldn't leave it up without comment. I don't want to do wrong by any of you. Can you share the video tear downs you found? I'm really looking forward to seeing more details on what we find as we dig in ourselves.
@@UndecidedMF We were to optimistic... if the solid state technology was here ,we would see it in cars...

Just sent the link in my previous comment. The chemistry wasn't the only surprising thing about this product. Seems the inverter being used in the battery is not that great in comparison to other options in the market.
th-cam.com/video/z8sVbwitrB0/w-d-xo.htmlsi=eZ9YnlJePC48K4HN
Figures there'd be some kind of "scandal" with the first solid state battery product lol
So glad I didn't pull the trigger on buying one.
There is no such thing as a solid state battery. It's literally just using off the shelf lithium batteries that have been sold for over 15 years. Just clickbait bs.
@@TexasStormChaser Wrong!
There are Solid State Batteries out there. The problem has been making them to scale and making sure they are reliable for thousands of cycles and at least 10 years.
@@Dreadlk Literally every lithium battery is solid state.
@@TexasStormChaser Lithium Ion batteries use liquid electrolytes, not solid
They are using standard li-polymer cells, while some others use LFP. Li-polymer is lighter, but lasts much less cycles, so the product will die real quick, like all power banks.
Yeah there's tons of these lol. There are currently zero large volume solid state batteries right now. There's tons of falsely advertised units. I caught one on fire on my channel a year ago.
You should open every unit you review. Theres tons of garbage out there.
Yeah polymer is not solid state 😂
Yeah the companies told me the same about the safety ratings. You need to put a drill through it. You can't trust these companies.
A PhD student?! 😂 Just open it up right now, takes five minutes. These companies are a dime a dozen. They are not special.
This is why I trust @WillProwse more than any other TH-camr for electrical reviews. He's not afraid of tearing products (and brands) up.
@@adriftatlas Nom nom nom nom (sounds of you gobbling his balls)

Feels like you *wanted* this to herald the beginning of Solid State Batteries, that you disregarded the probability of this being only deceptive marketing.
@@InspectorGadget2014 you wont be missed bud, comments that got deleted likely were hateful, including yours, which is unsurprising to see you still stew over it and unsub because of it.
@@ThermalSpace Innocuous comments get deleted all the time, don't be a bigot.
At the 14:23 mark you claim that Yoshino's battery "is safer too" when showing the comparison chart with LFP batteries. How did you come to the conclusion of this battery being "safer"? I just watched another person's video where they punctured the cells in Yoshino's battery and those cells started to rapidly smoke, exactly in a way the other types of LFP batteries would do. So how is this "safer"? Serious question.
If it were real Solid State, it would be safer. The other videos came later.
Do the "other videos" address that their safely claims are seemingly wrong too? I didn't see that on first watch just now @@BenH57.
Matt, just like I mentioned on your first video: Regardless whether this is solid state or not, the higher energy density comes from the fact this uses NMC cells and not LFP like the powerbanks you compare it to...
NMC cells have an average energy density of 250Wh/kg, while LFP sits around 175Wh/kg.
Unlisting and linking the original is great. You get the full value plus the update's value in this video, and the unlisted video now won't show up in the algorithm and deceive people, while it's still available for the sceptics to go through, but they have to go through this video first so they better come with points that aren't already raised.
I'm looking forward to the part 2, and I think this should be the golden standard of 'partially retracting a video which still has value'. Unlist the original. Update part 1 and link to the original, then work on a part 2. It leaves no uncertainty during the investigation.
👍 It's taking a while to pull part 2 together and I couldn't leave the original up getting served via the algorithm. Glad to hear you think this was a decent approach for transparency and handling it.
@@UndecidedMF Let's hope this video does even better than the original. Authentic, nuanced clarifications, retractions, corrections, and well cited fact checking really need to be amplified over other social media content. This is much harder to measure than simple engagement-based algorithms (primarily outrage and outrageousness), but given the existential threat that social media represents for literally every aspect of society I can only remain hopeful. Perhaps LLM AI models will reign in the accelerated pace our echo chambers amplify the worst of human nature and instead bring out the best.
Thanks Matt for risking the loss of income for this retraction.
Props I guess for taking down the original, but it's really the bare minimum required here. You presented a no-name manufacturer's marketing as factual proof and didn't do the most basic investigation to verify it. The little research you did do gave no indication at all that these are anything other than regular Li-Ion batteries with liquid electrolytes.
Bring more skepticism in the future. Do the work. Don't buy into marketing BS.
Timestamps for the new additions would be welcome for those of use who already saw your first video.
I just added some. 👍

And if multiple cells are involved and they are encased, the outcome can be dramatically worse.
TH-camrs shelling products with no research and being praised for admitting they didn’t investigate before is wild.
If you want a "light and dense" camping battery, the way to go is a 24V LFP. Many if not most things that can plug into a 12V cigarette lighter port are now designed to also work at 24V. 24V carries the power out more efficiently than 12V on the same wiring. Then you leave the power inverter at home.
Say you hook up my portable fridge. AC power is measured at 73W when running. DC 24V seems to be ~60W. Average DC draw is ~30W on 24V as in I calculate this number against the Wh rating of the battery to get total estimated run time on battery. So DC you cut out the conversion loss of say 10% and parasitic draw of say 5W to go from 24V DC to AC, you dump the inverter overboard all together, and you get rid of the conversation loss in the fridge from 115V AC back to 24V DC of ~20%. You may lose on average ~40% of your power between conversion loses and parasitic draw of the inverter, which is now all dumped overboard. Now say it just goes straight 24V DC from the battery to the fridge. There is a 0.5V drop from the battery to the fridge while running over the long DC cable that comes with the fridge. With 12V, you have a 1V drop and twice the current. So you go from a ~2% transmission loss to an 8% transmission loss going from 24V to 12V. So AC conversion ~40% loss. 12V is ~8% loss to go from battery to fridge. With 24V it is a ~2% loss to go from battery to fridge. 24V DC battery is the winner here.
Now what else do you want to power on your camping trip?
1. USB - USB chargers are available that very efficiently take 24V power and buck it down to your device voltage. For PD, the output voltage is typically 20V, so a DC-DC buck conversation from say 26V of an LFP battery to 20V is about the most efficient thing you can possibly do. Nearly 100% efficient. So again a 24V battery wins.
2. Dedicated laptop charger - Say you have a laptop with a dedicated power plug, not USB-C PD. A standard Dell power supply for example is 19.5V. Again going from ~26V of an LFP battery to 19.5V through a simple buck conversion on a buck-boost converter is about the most efficient thing you can possibly do. Nearly 100% efficient. They make a variety of these and ones that are "universal", so pretty much any laptop can be powered this way even if you don't do USB-C PD charging or it kind of sucks on your particular laptop model.
3. Starlink Mini - This can take a 100W USB-C PD power supply. Again 20V. So a 24V LFP battery to do this primarily doing a buck conversion (maybe use a voltage stabilizer) is the most efficient thing you can do.
4, Cell booster - They make these that can plug into a cigarette lighter port. I am sure you can find one with a power supply rated for a 24V LFP battery.
5. Cooking - Use a propane stove. Job done. No electricity needed. Anyways, bringing an electric hot plate or microwave oven is a lot more crap to lug around. Just bring a propane stove and call it a day. And you know for hot coffee, you could just boil hot water on the propane stove. This process does work without your electric espresso machine.
6. Lighting - USB charged lights. No AC power needed. Why would you fuss with a propane or white gas lantern? I mean an LED light you just press the button and it turns on and off. And why would you bring an AC lamp or something with you? You are camping here, right?
Really, what are you bringing an AC inverter on a camping trip for? Just dump the inverter overboard and then you have "light and dense". Certainly lighter and denser than any of these portable power stations.
@@ChaJ67 Holy Cow 🐄
Hey now...
Check out the Wacaco Picopresso....portable espresso machine. All you need is the boiled water.
There's also the Outin which you can easily charge. Option to use with boiled water significantly increases the unit's battery life if it doesn't have to heat the water as well.
Then there's the Aeropress. While not espresso, I'm just adding that there's kinda no excuse to not have excellent coffee anywhere...

A comment so good it should have been a video.
Honestly I've learned to never take your videos serious. Sent it over to a friend and we both were instantly skeptical. You really have to spend more time not giving crack pot science and scam companies a voice.
Great update. I appreciate your integrity and desire to get the facts right. It's part of why I subscribed to this channel.
Also, I have to say you have great production and audio consistency. Hearing your voice some time after the original recording back to back, I couldn't tell they were recorded at different times. Many times, ADR after the original recording can sound wonky. Good all around! Keep doing what you're doing.
Always appreciate seeing someone own up to being less detailed than they could be. This is how we all get accurate information.
Agreed! :)
Watched this update, it's good you published a qualifier but you really need some more reflection on why no deeper thought was done for the original video. Own your mistakes. Many of the people who watched the video and perhaps bought the product are likely never going to see the updated video. This is especially important because of the potentially inaccurate safety claims the company makes, which you don't even note in this update.
My biggest problem isn't that there might have been small mistakes in the video. My biggest problem is that we keep constantly, repeatedly, and clearly, hearing from you, that these new breakthrough battery technologies from the future that will revolutionize everything... are 2x or 3x battery density or charge/discharge speed. A 20% (or whatever) increase isn't revolutionary or a breakthrough. It's marginal improvements over existing products, and that's progress, sure. But it's just not what was promised by these companies and especially not by all your previous videos.
When we ask to see these revolutionary breakthroughs from the future, we want a 2x 3x 4x battery capacity on the same weight, or a battery with the same capacity that's 50%, 40%, 30% the weight of their competitors. That's what you keep alluding to, and we're still waiting for.
First off, I think this sounds suspiciously like a huge ad. That's very disappointing.
Secondly, you can't expect a first iteration product of anything to perform as well as the most mature and final iterations of the last gen product. THat's not how things work. First iteration stuff is sometimes even just on par with the previous gen products. If you compare the larger battery pack, there is substantial weight savings. Now that mass production is in full swing, there will be rapid advancements. Patience is not a virtue that people seem to even pretend to have anymore.
Regardless, this still seems like a huge ad and is very disappointing. I know he said he has no association, but something seems fishy.
I mean, the thing is we're not going to hit that sort of thing instantly. Like, battery tech multiple times better than it was 10 years ago, and orders of magnitude better 20. Since a lot of the individual components of a battery could be optimized or replaced, you're only going to see very slightly improvements year over years, that add up to batteries being that much better. But if you compare batteries that came out close together, they're going to be close in performance.
Ok sure but how many times have we heard outlandish claims and the only barrier to production was "scaling up"? I don't want a 10% increase in capacity - you can probably get this by offsetting a battery with lighter materials around it. I'm still waiting for the dozen 2x 3x capacity that we're waiting to come out of factories. Until then, I don't see the point. It's certainly not "revolutionary" in any way.
@@eslachance Chill bro. Not sure how old you are but remember first gen Li-ion batteries? They were markedly better but nowhere near as good as they are now. The tech will mature. If you don't want to "constantly" hear about emerging tech, then stop reading about it. Science takes a long time to become a product you can buy. That's how it's always been.
@@roots4x I'm chill, man. I'm not saying improvements are bad. I'm just relating that Matt is really quick on the "revolution" and "future", and has been taking about these batteries for years, and like I said, has clearly stated throughout these years that the biggest thing preventing commercial products was mass production and costs.
These Yoshino packs aren't much better, and they're not much more expensive, and my only point is that they are only a marginal improvement. It's an opinion, man, and I'm expressing it. If you don't like reading contrary opinions, it's also within your power not to read them.
You need to do better vetting of products before rambling on about them, taking companies words on things, and parroting them. You should be ashamed! Not praised for making corrections after the fact.
Thanks Matt for this follow-up. I always value your perspective.
Great job on actually responding to comments. Not just with adding to the forum, but going as far as to re-release video content with markups. very few content creators do this, so it is highly appreciated.
I saw this coming from a mile away when I saw the original video. I was waiting for you to tear the thing apart throughout the video. The fact that you keep saying its solid state battery without ever confirming it yourself was a major oversight. At least you're owning up to your mistake. Looking forward to the investigation video.
Did anyone else notice the lack of covers for the outlets/inputs? This should be a show stopper for anyone wanting to use this outside. Just don't do it.
I find the nitpicking about the definition of 'it's here now' really tiring.
Yes, of course you can argue that a product that has been shipped to a few beta testers is not 'yet here'. However, the product you show is readily available for everyone to buy, with the only limitation being the production capacity of Yoshino.
If it has been sold 3 times or 3 million times shouldn't matter. Ferrari's are not the dominant cars on the roads, but I've never heard someone say Ferrari's 'aren't here yet'.
Another youtuber also disassembled the power station. The model number of the batteries are easily seen; a quick google search of the model number brings up sites selling them as regular old lithium ion batteries.
I’m glad to hear that he delisted the old video. While caveating the original claims is a good start, I am still disappointed that he focuses only on whether the company made misleading claims, but does not take any responsibility for his role in spreading them. This is claimed to be a first-to-market product from an unknown company that registered itself only two years ago. Claims made by an established brand with a reputation should invite a healthy scrutiny, but claims from a new brand with no reputation-let alone one with revolutionary claims-should be met with much greater scrutiny.
When a content creator gains a significant following, I believe there is a responsibility to prevent the spread of misinformation and do at least some due diligence before presenting products that may be seen by millions. This doesn’t necessarily mean that he should’ve torn down and tested the product himself, but it should at a bare minimum include researching if claims have been independently vetted and verified, and if they have not, to simply present them as unverified claims. I hope this experience informs the way in which he presents technology in the future, and in the future investigation video he is willing to be transparent and acknowledge his mistake.
There is absolutely no chance that a no-name NMC-based battery is going to last 4000 cycles or anywhere close to as long its LFP counterparts, regardless of its (probably not) solid-state electrolyte. My guess is that this battery is a semi-solid-state battery, which doesn't have the core benefits of the all-solid-state batteries we keep hearing about. Even if they are telling the truth about the battery chemistry, they are 100% lying about the longevity of the product, which should take away any credibility they have for the rest of the spec sheet.
Not even that. This video.autostarted after I watched a review of someone tearing one down and proving they just used standard lithium cells.
Saw your first video in automatically thought it was a red flag that the solid state batteries cost about as much as the old style batteries.
Thanks for marking the updates so as someone who watched the old video I could just see what’s new without needing a full rehash
I told you so. I and many others warned against taking the company's word at face value for claims that sound too good to be true and as the first major breakthrough. Especially when their product doesn't have the cell spec sheets to go with it and the specs of the finished unit is worse than other units using conventional cells. It was also a company with zero track record.
Now with other youtubers doing digging, this is yet another Chinese company (using a California warehouse address) selling a product with a cell with liquid electrolytes/solvents (so not solid state).
I hope next time before doing a similar review, you will either do your own teardown or wait for others to do a teardown to confirm what cells are actually in it. It's ok to make a mistake if you learn from it.
So happy to see actuall followups and corrections. this is what makes reports, channels, etc actually good and reliable. No one is perfect but most newsoutlets and youtubers don't follow up at all, let alone when they know there is important information they should be adding. Well done thank you and the team for all the hard work
Really appreciate the way you've handled these issues Matt!
Wow. Thanks for the shout-out, Matt!! 👍
Good on you for the transparency efforts
This never should have been re-uploaded, updates or not. Its still a huge marketing piece for a product you clearly do not understand.
thank you for posting chapters for the future matt updates... I watched the original and didn't want to look for those updates... and thanks for the transparency on these updates... I look forward to the follow up info!!
This is why you need to check things before blindly regurgitating what you are told.
No matter what its super sketchy that a new company with no other products pops up out of no where, and claims to have the only solid state battery on the market for months and no other major manufacturers even announces any competition. Yeti, Anker, or Jackery would have something at least announced by now. The fact this has sketchy things popping up about it doesn't surprise me, and I will never trust a company that even partially lied about their first product. This was their introduction and they failed.
Love the integrity man, and the willingness to do the full investigation. True in the spirit of your channel.
The one thing about all of these manufacturers that drives me crazy is how they market battery power systems as "generators". I would rather buy from a company that knows the difference, and doesn't assume that I'm stupid.
I am SO HAPPY you did a follow up on Yoshino products. I will be purchasing a battery backup solution soon and was leaning towards Yoshino. But, I will be happy to wait before I drop thousands of my dollars on false claims.
Side note: I tried to contact Yoshino on getting their B4000 at the discounted Amazon Deal price ($2,699) and never heard back from them... Sigh...
Thank you Matt for staying true to the facts and updating all of us, rather than just moving on to the next thing and ignoring any issues that were brought up. I'm glad there's creators like you who take responsibility and pride in their work to get things right and set the record straight.
Thank you for making this kind of correction.
You did great breakdown of power/weight in 10 min mark. It was transparent and well explained, that you mean whole unit you are using, not battery cell density only and is what is needed to make buyer decision.
3:50 The first red flag for me was how long it takes to charge. SS batteries should charge considerably faster; it is one of their primary advantages. Right now there seems to be little reason to spend a premium for nearly identical performance to other brands on the market. And if the company is being dishonest or at least dodgy about how they classify their tech, I don't trust their claims for cycle count and longevity. Thanks for the update. I'm passing on this brand
th-cam.com/video/z8sVbwitrB0/w-d-xo.htmlsi=YWfNAnnX4KNwZZbq clearly not solid state for multiple reasons. The individual cells inside of this has a part number that leads directly to a tech sheet from a standard lithium ion battery. Furthermore directly from their website a breakdown of the build of the cell clearly shows organic solvents not inorganic solvents. And in this video he punctures the cell and it ignites on fire..
Thanks for the correction and honesty. Super important.
Excellent followup, I was very excited to start seeing SS available to purchase soon™, but it seems we still have to wait for the tech to be more mature and more information is generally available at a consumer level to decide what is SS and what is not.
My only suggestion for your next video would be to measure and test your units W/h and compare with the given spec (heck adding at least one of the lithium batteries would be good). We take at face value what these companies tell us about capacity, but reassurance for consumers is always good.
Thanks Matt for doing this UPDATE, and providing transparency into what is known, for the Undecided community.
It would be nice to have more clarification on what the battery industry considers "solid state". My understanding that solid state is just a reference to the electrolyte used in manufacturing the cells, which is a gel, or a dry paste. This is said to improve assembly efficiency in manufacturing. If there is not an industry conscientious, that would also be good info.
As far as cell energy storage capacity, it is my understanding it is determined by the storage capacity of the anode and cathode materials. Storage capacity of anode and cathode need to be similar, otherwise the higher capacity material is limited by the lower capacity material.
Matt, it would be helpful to touch on how all 3 components (anode, cathode and electrolyte) effect cell capacity. For example, if a dry paste electrolyte takes up less cell volume, then the surface area of a given volume cell can have more cell layers, thus more surface area. (ie: increase capacity).
The other area of interest is "solid state" cells are suppose to have much higher cycle life (full charge/discharge cycle counts), as the thick gel, or solid paste type of electrolyte is suppose to stop hair-like dendrites from growing between the anode and cathode. This is harder to verify, as it requires putting multiple cells through an endurance test to measure how cell capacity decreases over time, under different temperature conditions. (cold, near room temperature, and warm)
Awesome comment and suggestions to cover in the follow-up. You and I are thinking along the same lines. I do think there's a big issue between what is technically a solid state battery vs. perceptions, so I'm going to hit on that in the video with some experts to chime in on that (trying to get that lined up now). Once we have that baseline established we can explain why Yoshino is or isn't a solid state battery. As frustrated as I am at myself for ending up in this situation, I'm also loving it. It's a great learning opportunity and I can't wait to share what comes out of this.
This the best attitude .. "It's a great learning opportunity." The technology is just making its way from the lab into mass production, so there is a limited amount of good information. Really appreciate you taking the extra effort to better understand and share to educate a larger audience.
I'm glad you posted this update; it had me worried when the previous version disappeared when it did.
Yoshino’s power stations all use batteries with an Inorganic Polymer Composite electrolyte that is recognized by the scientific community as “solid-state”. Yoshino is the only company offering commercially available power stations that fit this description.
One major oversight Matt- You referenced operating temperature ranges, but not CHARGING temperature ranges. This is critical information for someone looking to set up in an unheated shed, barn, garage etc., where charging below 32 F would destroy most Lithium batteries.
This is my main problem right now " Some residual binding fluid, composing less than 5-10% of the total battery’s volume, remains as a result of the manufacturing process." I would like to know what this residual binding fluid is and if it is in any way bad and could cause the battery to catch on fire.
Thank you so much for the update, I'm looking forward to the things you're still working on updating. Also, I hope the TH-cam algorithm is nicer to you for this update. Or to put it another way, please forgive me for not watching the full video and clicking through to the update segments. Hopefully this comment will help offset my lack of view time =).
What was the point of an update without the testing results? Just wait until you actually HAVE all the answers and caveats rather than making a halfway-fixed video.
D'oh! Pushing that hype train can lead to getting run over by it.
Half done review. Where is the information on cycles other than saying it's superior? Simply saying something is superior doesn't make it so
Let this be a lesson for your future videos. You ought to hold yourself and your videos to a higher standard.
Sorry to say, Your video Sounded more like Advertising this battery rather than really telling us about the question that you highlighted in the video title. Sorry but one dislike from my side.
It didn't pass the penetration test, it is not solid state - period. This update isn't updated enough to truly report about this battery. The ground news sponsorship is hilarious when talking about bias.
Penetration testing isn't how you determine solid state or not (solid state batteries can still catch fire ... just far less likely). As I stated in the video, I'm digging deeper into this trying to figure out why Yoshino is even trying to claim solid state. My investigation is almost complete, so the follow-up shouldn't be too much longer. I've been talking to a lot of experts, getting additional lab testing done, etc. So if you want throw shade about being biased, yeah ... I'm trying not to be biased in my investigation and being extra thorough to cover all the bases. Far better than doing unscientific penetration testing in my driveway and calling it done.
@@UndecidedMFwhat you are saying is not entirely true. I suggest check your source. I work in the industry.
@@UndecidedMFBeing thorough and covering all bases should have been done before making this video claiming Yoshino has solid state battery packs. I generally like your channel but it is sad to see someone such as yourself do absolutely zero research before promoting a product like this. People trust you man and this is very disappointing. Hopefully you can recover from lying to your viewers as I like this channel. But it's going to be very hard for myself and others to take you seriously from now on.
@@pnwlifevlog If you’re referring to my statement that solid state batteries can still burn, they can … just far less likely to. Polymers can burn, so a polymer solid state battery can still burn. I’ve spoken to multiple people in battery research and development about that.
@@cameronmacdonald6525 if I was lying, then you mean I knew this to be untrue and still published the video to deliberately deceive people. I did not. I should have dug deeper, yes, which is why I published the correction and am doing a crazy deep, deep dive investigation now. This isn’t as clear cut/simple as many think it is (ie. “is Yoshino solid state or not” … it’s actually a fascinating broader issue in the industry), but regardless this was a learning lesson for me. Nobody is perfect and I can only admit when I missed the mark and do better next time.
I had a hunch when the original video was posted that we were gonna come to find that everything wasn't what it seemed.
Looking forward to the full report. I honestly hope that actually is a solid state battery.
Just a piece of info for everyone as I use and test these products regularly,
So do you know how many classes of lithium batteries there are?
Did you know LFP falls under a class of lithium ion batteries?
Did you read every individual ingredient in the MSDS sheet to categorize what percent makes it NMC or solid state?
Are you speculating just because it says lithium ion?
If you are a professional I won’t doubt you, but since there are several classes or lithium ion batteries I would rather have the rest of the facts verses just an assumption. Hence a couple of us are trying to get the correct info before we come to a conclusion.
To many have already concluded with no factual material yet except for what we have seen. But let’s wait to hear from the experts.
Hopefully in a few days or next week I’ll have a follow up video and maybe others will as well.
Battery make up and chemistry is what’s important. Not the class it falls under.
Wrong! There are a set of physical and minimum electrical Standards that have been presented by the companies working on SS batteries. This Battery fails on every promised feature. Also did you watch the TH-cam Video by "bigtb1717"?
He pulled the Powerstation apart and showed us the Labels on the pouch Cells. They are standard Li-ion Pouch cells. I don't know what more Matts "Team" are going to uncover since the markings are right on the cells. They also Catch on Fire in a nice spectacular way just like a typical Ni-Ion cells.
Did you not watch both of my tear down videos ? Are you a battery expert ?
Just because he shot a arrow and decimated a battery pouch which he actually needed two arrows, I did several puncture test with nails, and no fire or explosion happened with my pouch cell from my Yoshino unit.
I did a full dissection of the battery. Battery tech and voltages change with tech.
So unless you know a 100% for sure, or again are you coming to a short conclusion?
Do you know what makes the exact difference from a NMc batt and a solid state?
I know these pouch cells absolutely do not react like a NMC battery. And it’s definitely not LFP
The real question one need to ask is, based on the product, and most importantly how it is used, do you really care if it is solid state or not AS LONG AS provides the needed service. Regrettably the click bate videos that push the "solid state" idea as some kind of panacea have created this "solid state" mania and such should take responsibility, but regrettably that will not happen as that will damage their cool tech image, which is the bread and butter of the cool tech click bate industry.
I think it originally said it was a hybrid solid state, and my guess on that was that it just used less liquid electrolytes, but i was still hopeful it would be different, which is why i didnt say anything negative on the original video.
My problem has been that it still uses nickle and cobalt which until we have testing on this differetn formulation, we'll have to assume the similar 500-1000 cycle rating as other NMC batteries, as opposed to the 2000-6000 cycles of LiFePO4.
Now that others have torn them apart, it doesnt look like it has that much less electrolyte either but I'd still like to see more testing.
Love the update . That why I love this channel. Looking for correct information so I can make better choices going forward. Big Cheers from NY !
This update was the way to go. Kudos to you, Matt.
On a side note, I was wondering the other day what happened with space tourism. I guess millionaires keep getting in orbit, but it seems to have completely disappeared from the news.
As a regular bloke who hopes to still be healthy enough by the time I'd be able to afford a zero-g weekend in my old age, it'd be interesting to see an update video on the subject.
For orbital (ie., longer than 5 minutes!) space tourism, the only options right now for "a zero-g weekend" are Dragon & Soyuz. New Shepard & Virgin Galactic are simply 10 minute hops total, & basically straight up & straight down again, barely touching the Karman line. (or not even touching for Virgin Galactic) Dragon & Soyuz will set you back US$50-90 Million a seat, so not really an option for even remotely close to a regular person. Sierra Nevada's Dream Chaser crew version will also be in this category when it comes online probably late in the decade (for crew - cargo version is due for first launch in the coming months).
SpaceX's Starship is the only thing in development that has any hope of getting anywhere near "regular person" holiday price range. It's another economy of scale thing - most will be very surprised how big it is when they see the eventual cabin tour videos. (more volume than an ENTIRE 747 pressurised fuselage volume!) They MAY eventually get ticket prices for short flights down to the low 6 figure range - cheaper than both New Shepard & Virgin Galactic, but for a couple of days fully orbital. Nothing else I'm aware of in development comes remotely close to Starship's longer term price possibilities.
You might want to follow the Polaris Program, lead by Jared Isaacman, partnering with SpaceX. First flight (on Dragon) is coming up soon (currently late this month [26 August 2024]), called "Polaris Dawn." They will be doing the very first commercial spacewalk. Flight 3 is aiming to be the very first Starship only crewed mission - launch to landing - though that will likely be a couple of years away. After Polaris flight 3 is when the fun really begins for space tourism! (& the commercial space future in general, that all of us scifi fans have been waiting decades for)
@@BrendanBurwood thanks a lot for the long answer
You're clearly not only interested like me, but also much more informed
@@drillerdev4624 No probs, & yup, I've been following SpaceX since the Falcon 1 days (still kicking myself for not going outside 1 hour after the first Falcon 9 launch - would have been a specatular sight [large glowing spiral plume in the pre-dawn sky], & even made the news). SpaceX has been the first company in my near 5 decades that has the promise (& leadership drive & ambition) to begin delivering the scifi future we've been promised for decades since Apollo times. Their success has also paved the way for several other companies with great prospects too - Rocket Lab, Firefly, Relativity, Stoke, Astra among others. (Still waiting on Blue Origin to actually send a gram to orbit before I get excited about them again!)
Hmmm, seems TH-cam has now finally shown the comment above, so I've deleted my other 2 later attempts.
Or not. It seems you need to use "Newest Comments" to see it. Come on TH-cam! Why?!?!
Great news. Not that you were possibly wrong or deceived, but that you made corrections and doing a deeper investigation. If only all the reporters did such a job truth would not be so hard to come by these days.
thanks for the update. I love it when people do updates when things change
myself when looking for a battery I am looking for something that can power my computers for an hr or two (3 about 3 year old full sized computers) I already have something backups for my medical equipment that will work for 3 days+ but that is also a 5 year old system that still works fine.
Maybe you should have checked it before you made the video to begin with?
Two important items related to solid state promises of the past that were left out:
How does the cycle life compare to LFP including tolerance to deep depth of discharge?
How does peak power compare as well for LFP of the same size?
Thanks for the update Matt.
Glad that you've released a follow-up.
The battery cells have text and a QR code that identifies them as LIPO batteries. The company's own web site has a graphic that shows the batteries are not solid state. The other TH-camrs that did tear downs all concluded that they they are regular old LIPO batteries. They cost as much as other LIPO batteries. They have the same performance and specs. They burst into flames if exposed to air like LIPO batteries. Is any of this conclusive enough for you?
I almost bought this based on your original video. Glad i didnt.
While I'm glad you're updating and correcting, hopefully there's a lesson here for someone with your size of platform and the reach/influence you have. With such an outstanding claim like solid state, it was lazy to not do this research and legwork before initial publication.
Regardless, you're doing the right thing now and that deserves praise, so thank you.
Wait, Matt with another battery video? Smiles....
Thank you for the clarifications and for keeping things real and honest!
This has happened so many times for decades. New technology with high potentials around the corner. Companies doing their R&D are timid to go public. Then a company drops news they are selling. Turns out it's a scam! But the company selling the scam (unknown at the time), finally encourages those in R&D, to go public. The hero no one wanted.
Great post Matt. I appreciate the update and look forward to your next post. On the surface it appears the solid state claim is a stretch at best. I’ve heard this product more accurately referred to as a semi solid state or hybrid battery. Either way, introducing your company and product with misleading information is a really bad idea.
👍 I agree with your statement. If it turns out this is a semi/quasi solid state of some kind, it's going against what the public thinks/knows of solid state (that's a problem). I'm keeping an open mind until I see the lab results from my friend.
This is a great way of doing it. The only thing I would say is change the thumbnail to say or indicate some way that it's a re-upload. TH-cam kept recommending it to me and I'm like stop showing me some thing I've already seen. But then I saw the other video so it popped up again I thought well maybe double check.
Yeah original video goes unlisted and update the description then new video goes up I think that's the way to do it. As the original video was pretty good apart from the information that needed to change. And I want to support a reupload with good views but need to know that it's a re-upload to click on it.
At the current state of solid-state technology, no mass-produced battery is completely liquid free. Some residual binding fluid, composing less than 5-10% of the total battery’s volume, remains as a result of the manufacturing process.
“Serious issues with how they marketed it.” Yeah. They lied. Thank you for posting the update/retraction. Hopefully any TH-camrs that took a sponsorship from the company will also post retraction/updates.
Very curious if any of the noted manufacturers of the packs are also lying.
I tried to buy one of these from Amazon after your first video, but Amazon cancelled my order because of stock issues (they said).
I’m proud of you for adding detail. - a battery scientist
Thank you for updating this video. I been looking for a ss powered charger and didn't want to be ripped off
The most important question for the end consumer is not if the battery is solid state or not.
It is the observable and repeated difference in the performance of the system. As compared to what has been historically available in the market.
As of this moment, from what I have seen. A real world comparison between Yoshino and others has not yet happened.
Thanks! Look forward to what you find out.
On a more positive note, Samsung just started delivering their first round of Solid state batteries to an undisclosed car manufacturer, currently the Samsung battery is at 500Wh/kg at the pack level.
Their pilot production line is already up and running, and they expect to be in full mass production by 2026.
Do have a look at that one!
Good stuff. You don't just want ion energy density, you want rapid rechargeability to maintain work/time. A muscle ion processes tends to be stronger than a electric motor of the same mass, because it can continuously restore potential, while diffusing energy, therefore ion gradient energy density is a narrow focus, because the goal is work/time. Because you don't need (1 type of energy density) not to just have all the energy density in the form of (ion gradient energy density) considering work/time, because there is a voltage to consider in terms of the appliances being run, it's enough to have faster rechargeability, and chemical potential energy density, rather than high ion gradient potential energy density. Because a battery is not meant to diffuse it's power all at once, therefore high ion energy density potential is irrelevant and not practical, it's a error in measure of a batteries capability, because that's not what batteries job is, rather work/time is a batteries job. There are other energy densities that can be stored. Biological systems have many types of energy density storage, these energy densities are one a type of conveyer belt that resources the ion potential progressively as charge is diffused. It needs to be like a piston, cycle around from potential to release potential to release, where the oxygen and gas in the motor is not a total measure of the potential of the motor, but rather there is a gas tank that is not being considered. It's about the non-frictionless transfer between multiple types of energy density, and the efficiency, and sustainability of tech without pollution or drudging up the sea beds, or slave labor in Africa for rare earth metals, and it's about progressing science and engineering past the community of peers one eyed cyclops mode nonsense.
What happened with the seperate investigation video ?
good response. I thought the og video was a bit half ass. i appreciate the effort to be more rigorous
Thank you for the update. I really appreciate the integrity it shows.
There are many misconceptions of what “solid-state” actually means. Yoshino adheres to the commonly accepted scientific definition that a solid-state battery is one that uses a solid electrolyte in place of liquid or gel electrolyte found in traditional lithium batteries.
Matt.....one thing I am sure of that I got my B330 for 149 dollars so I got a good deal and I got my B4000 for just over 2600 dollars........I got free shipping on both and paid no taxes.
Why there is always a catch when there are chinese companies envolved? Is there an honest chinese company? Yoshino is not from California or Japan.
It's automatically a red flag for me when I see a Japanese name with HQ in another country.
Just to clarify: they actually are headquartered in California. The manufacturer is in China.
@@UndecidedMF Okay, then that's like most brands. Was there a reason for them to go with a Japanese sounding name? Like CEO or something like that?
@@UndecidedMF Get used to get lied at, these type of companies are appearing everywhere. Having an address in the USA means nothing.
Headquarters in CA, Designed in Japan or supposedly but manufactured in China. Good update.
Thought it was sloppy of you to not actually investigate properly 😕 but glad you are making corrections. Well done on not being irresponsible.
P.s they are definitely not solid state batteries, it's still definitely lithium that just uses a polymer electrolyte. It's not solid, it's a gel
By lying to his viewers faces, most of whom would have bought this product after the video was posted, he is most definitely being irresponsible.
