Like every new battery announcement, Ill believe it when I see it in production at scale. Have they really solved the issue of Si expansion? Tesla thought they had it solved and they apparently didnt. And is it cost competitive? If it costs twice as much existing cells, it likely wont make much impact except in aeronautics where weight is more important than cost. How is cycle life? Im very skeptical of new battery announcements at this point. I wish them well though!
Yeah.. didn't hear anything that would convince me it's actually real, more lab stats. Felt pretty wishy-washy for a Munro video 😒
Cost isn't such an issue if graphite became inaccessible to the global market because China cut off supply or due to political issues limiting trade.
It’s difficult to accept when the “fake it to you make it” strategy has been overused in this “pump and dump” tech world.
Exactly.
I used to follow battery technology like a hawk and would get so excited. Then I realized that it’s relatively easy to produce a better battery in a lab, and that the hardest part of new battery tech is to scale it up and provide high cycles in real world conditions. I hope this one succeeds but it sounds very similar to many other breakthroughs that came before it. I guess it’s better than a professor in a lab announcing it at least (which generally means that it’s likely never going to become commercialized and is probably being announced to secure additional research funding).
Did I miss cycle life reference? Density means squat without long cycle life.
and cost per kWh
No you didn't, he literally said nothing.
More pipe dreams as far as I can tell, not what I'm used to from Munro..
@@PhiTonics Makes you wonder if this was a sponsored presentation
Adding resin to hold together silicon likely increases internal resistance, which means less power density, not good for cars. Also likely significant cost penalty due to complex mfg process.
Cycle life won't matter for certain applications. Think rocket steering, etc.
Can it be mass produced at a competitive price?
This sort of thing pops up a few times a year then vanishes like ice on a stove
400Wh/kg is beginning to make its way into production (still very expensive). I think a decade from now, 300Wh/kg - 350Wh/kg will be common place.
Aircraft grade today . Car in future ( Sandy mentioned the VTOL here)
This is aerospace
yeah, but when its at munro its more promising. Charging / discharging speeds? Ageging and so on...
@@OldSkoolUncleChris This would be great for stationary storage as well. Smaller footprint for the same capacity.
I presume this wasn't a paid sponsor, but I'll tell you, it has the feeling of it.
Little information, so sparse it hardly filled a minute run time, but high praise without any real information on the company, how many they've made, what they're in, etc.
I do prefer you spending some time with this tech to tell us about it.
If I wanted short clips and bits of information I can get that literally anywhere, your value is indepth knowledge, not the latest press release from a company no one's heard of, making huge promises like so many before.
Just my 2 cents, I do appreciate you.
It would be interesting to know how many things mentioned, such as this beta product, VinFast, Zeta, etc. made payments to get space on Munro Live. I know Munro Live isn’t a charity and I’m fine with sponsorships to get products mentioned provided we know that. There’s difference between “I found out about this cool product and I want you to know,” and “The maker of this product says it is cool and paid me to tell you that.”
Always sounding like a sales pitch,and everything is brilliant,and impressive...shill is another term. And maybe one day munro dudes are in trouble with sec or other entities for insider trading? Or stock manipulation.
The beauty of this is even if the batteries cost 2X as much, you only have to put half of a normal battery pack in an EV to get the same range, so the cost would therefore be identical on a per car basis. But the weight savings would also be enormous and beneficial to efficiency. Hoping they can scale big time.
But if it costs 2x as much per kWh, your math falls apart. The battery will weigh less, but will cost much much more. This would still be a great application for ultra range vehicles and aircraft, despite the cost
@@gemini86 the optimist in me would hope for 2x cost per cell, as 2x per kwh would mean each cell would be 4x more expensive than traditional cells. Hopefully they can make it price competitive at mass scale.
@@gemini86 With a smaller battery you can offset some of that cost, as the pack will be cheaper, and you can use less aluminum/composites in the car generally to hit reasonable curb weights.
They said it will cost about 600$ per kilogramm, lithium is 42$ per kilo, please forget the 2x dream, welcome the x14 reality
same capacity Less weight mean more range . Am I right ?
This is absolutely insane. Was not expecting anyone to pull this off yet. Incredible!! Next step, large volume manufacturing and calendar aging rate. Looking forward to future updates.
This can change so many markets. It's insane to think about.
This is great news for us, second life battery people: maybe good cells will flood the market and we can build our home energy storage devices even cheaper!
The cost will be more than you are expecting. 5GWh is so small it will be super niche.
@@LithiumBatteryGuy absolutely. But I'm thinking huge step for electric airplanes
@@LithiumBatteryGuy If it works, there's going to be plenty of capital to build out more capacity. They will initially target the highest-margin applications - aviation and other niche stuff - but that's likely just the beginning if the tech is as good as they claim it is.
Just in December they hit 390 wh/kg and it passed the military requirement of not igniting when a nail is driven through it in testing.
Just imagining that requirement being added by an upset general who's office built of surplus battery packs burnt down after he hung a picture of his favourite M4 Carbine on the wall with a nail.
@@DUIofPhysics I think it's just generally to test punctured batteries, but your storie is much more. Believable.
Challenge Accepted , captain HAMMER will test.
Whow that’s some increase, let’s hope it’s for the real world as that really does start to change everything.
Seems like a bad, committee-driven requirement. If i mad a battery with 5 times the density then it would be useful even if flammable.
i thought that was corey.. i mean jordan. :D
good info, cool to see this tech take off. i hope its reliable with good C Rates
keep us posted!
Wow! Would love to see this battery. Seeing is believing! Lotsa love to you and all the Munro Live community from Toronto.
Hopefully we can go take a look! Thanks for watching!
@@MunroLivewon't you show the fans the rest of what the CaliforniaNazis is hiding?
Get your little buddy at McDonnell Douglas to show us 🇺🇸 some breakthrough classified propulsion technologies 😅? Wtfe
Who's got the iron man plasma reactor tech? I know one of your elitist dark lord bosses has it.
@@MunroLive so proof of concept: ✅
Proof of scale: ??
Proof of durability: ??
@Munro Live its probably bs does mps the firm that did the testing even exist?
The $64,000 question is: when will this be available at scale at a price people other than the Army can afford?
No the $64,000 question is how much more will u end up paying when the ev tax gets implemented...meanwhile I'm still rolling in my 80s and 90s jap cars STILL more reliable than anything in the last 10-15 years ..and since I'm not paying $64000 for a ev how much driving can I do for that ..I estimate 7-9 years of non stop driving for $64000
Scaling to levels the army can afford for larger vehicles is already a big step.
Only Army could afford to create a GPS space system. I think everyone can afford to use GPS now
@@UshankaShow A lot of technology which has civilian benefit was jump started by though military investment to achieve economy of scale. You won’t find me arguing against that. My question was how long is it going to take?
In the case of GPS, it was almost 25 years from the beginnings of development until the civil sector had a fully useable product (When Clinton’s executive order decommissioned selective availability in 1999). I’m not sure exactly when the design decision was made, but it was pretty early in the development of GPS that it was decided to have both as coarse civil sector bit stream and a precision enciphered military bit stream.
As a side note, the first civilian GPS receiver I owned was in the late 1980s, was expensive, took about 30 minutes to acquire satellite lock, and could be off by up to 1/4 mile randomly due to selective availability. The selective availability really messed up urban street use and even made GPS somewhat risky to rely upon for staying in a channel for maritime navigation. We’ve really come a long way for satellite assisted navigation in the last 35 years.
Not for another 30 years.
I have built silicon pouch cells that are about 500 Wh/kg. The trick is can they last and can you scale them up. I’ll believe it when I see somebody measure parasitic heats or give me a coulombic innefficiency / hour value.
+1 ... Thank you, Sandy and Anthony ... Brighton, CO a Denver area city....
It took a day for the memory flower to bloom....this is wonderful news, more power to Amprius and all who sail with her! Thanks for the heads up. Congratulations to Antonio and team...To the Moon! ♥
The cutting edge is where we want you Munro and associates 👍🏻
Sounds great. Eyes opened and hopeful.
Thank you for the update! Awesome energy density!!!
Great to see these breakthroughs. Even though many do not make to market, it's important that we can see what's possible and maybe we can achieve them in the future. Sandy mentioned the aviation use case, which is perfect for the VTOL taxies in development as well as drone delivery.
First thing I always ask with batteries is cycle testing. You can get a ton of power from a lithium cell, once. Getting it for a million miles is the hard part.
Still this kind of high power low cycle life is perfect on military drones! Most of them are single use only.
@@AdlerMow - then primary cells, or other chemical energy sources have all the advantage, totally different use case, ie. not the rechargeable world - noting that the single use devices you mention are more in the arena of guided munitions, not true RPA/UA's.
Getting a CAR to last a million miles is MUCH harder. By the time you drive that many miles you've replace the vehicle at least once with all the parts replacements, probably at least one or two wrecks with today's driving and no not even driverless tech can get you out of every bad situation that other drivers create, so you've even replace body panels.
I could care less about a one million mile battery pack because I'll NEVER get more than about 150,000 on a vehicle, except once in my life where I inherited a family vehicle from my brother who got it from my Dad and it made it up to about 200,000. So, if you have a battery pack that gets you 250,000 miles you've met the needs of probably 95% of the population and for the people who expect 1 million miles from a battery pack, WTH you driving now that will last 1 million miles? NOTHING.
@@johndoh5182 True, but we're talking about batteries. You can rebuild a car around a battery pack, just like any long lasting drivetrain.
@@johndoh5182 Ive driven a dozen vehicles past 1/4 million miles, its not hard
THANKS MUNRO 🤗👏👏👏🔥HOT OFF THE PRESSES NEWS 💚💚💚
Awesome NEWS!!!!! This is a game changer for heavy duty trucking
LOVE THE SHOW 👏👏... HAVE A BEAUTIFUL THURSDAY EVERYONE ✌️
Surprised currently only 367K subscribers. Deserves to be 3.67M subscribers. Definitely Subscribed and also Liked.
Viewed a lot of previous teardown videos which were highly informative.
Learnt a lot about how products can and should be cost effectively made while at the same time improving efficiency/quality.
Love how bent out of shape the old man gets at people questioning him, and here he is just presenting some company's vaporware PR material for them.
Great news Sandy. Thanks.
big news!!that will get the industry moving!! congrats!👍
Sandy - thank you for keeping me on the cutting edge.
Sandy been honestly keeping most of you in the dark 😂
Thank you!
Exciting times on so many levels.
Thanks for the info. I look forward to hear more about the battery. I enjoy hearing about breakthroughs in technology. I hope it works well.
I know it's not big bucks but this battery type with a hairpin motor would be big improvement for E-Bikes. For example same weight and double the range. Or just less weight.
This is exciting!. Also, knowing that you have a Lucid and Hummer drive units and batteries for deep dives.
Great news guys, your hard work has paid off.
Thanks for sharing the info can't wait to see your meeting with them
Wow great news, a breakthrough with new tech.! Thanks for sharing and we will hope more news soon.
Thanks for watching! Hopefully there will be more to come.
It's not up to Sandy, it's up to his CaliforniaCluxClan bosses 😅 as to what he gets to show and gets "briefed" on.
@@MunroLive better be more to come, like I've been saying THOUSANDS of pages of declassified r and d reports going back to the 1950s from your California nazi buddies in aerospace and automotive proving you and Elon musk is blowing smoke up the publics azz, everything from high density next level battery technology, to high density hydrogen technologies to new exotic propulsion technologies. If you and your team don't know about these things it's because you are a compartmentalized tool and have no business being a youtube influencer. Tired of you guys gaslighting the public.
@@MunroLiveI highly doubt sandy Munro knows much outside the number of bolts 🔩 on a 1984 Ford F150 because the truth is 99% of the "engineers" of these scum bag black budget corporations and companies are all compartmentalized and don't know much of anything outside of their own programmed positions but he obviously is in on the narrative of what the elite bring out to market and say. I'm sure their are a number of advanced battery and hydrogen technologies he knows about but isn't allowed to mention. It's a Shame, I thought the old man was human lol 😆 😂 😅 boy was I fooled
It's funny to listen to Munro bring on old timer guests who are usually senior engineers inside these corporate public scam companies complain about how the "elite" would not allow any changes to the way things are built and done. Innovation was frowned upon. NO 👎 NO! you can't do that is what I've heard over and over and over from these guys.
Why do you think that is? 😅behind the scenes they are funelling trillions into secret r and d of exotic propulsion and energy generation technologies.
Who wants to give up that power, money and secret? Lol 😄 😆 you let the public monkey 🐒 engineers innovate 💡 too much they might figure all this out and we can't have that so we must make sure for the next 100 years we make one man pop rivet by hand 1000000000 different pieces of beer cans together we call 📞 a aircraft so they are too busy and programmed to think of anything else. 😉
It's a sad reality that even the people I'm supposed to look up to for mentorship, inspiration and integrity, I'm always finding out they aren't the people I thought they were.
Very curious I wrote this on my own channel nearly 24 hrs before you dropped this video and wouldn't you know it...
Ole sandy and the CaliforniaNazis decide to go balls to the wall 🙄 BREAKING NEWS AND BALLS 😅 with a new higher density battery chemistry ⚗
CaliforniaCluxClan can do better than 200% 😅but I'll take it, but I expect more "classified" energy storage and generation technologies to be rolled out,
This secrecy of these technologies is RIDICULOUS
Thanks Munro for further concreting my suspicions of you.
Can't trust anybody can you?
This is huge. People are always saying some new tech is a game-changer but this is seriously, genuinely a game changer.
Wow thanks guys. I love the work you .
even if it's significantly more expensive, still seems like a slam dunk for planes
not really, a 20 ton battery insetad of a 40 ton battery isnt really that relevant
400 is where large electric planes are feasible. 500 means long haul flights are coming much sooner than expected
@@thomasreese2816 sir, this is factually incorrect
even for excavators, batteries are simply too big and take too long to recharge, hence hydrogen cells or hydrogen combustion is under development. JCB in the UK in in the advanced stages of testing Hydrogen ICE for their heavy machinery
batteries have their limits, for electronics - sure, for small cars - it's already a stretch, imagine something bigger
perhaps the overly optimist source you are quoting from refers to niche smaller planes (by calling them large they mean not 2 seater planes)
my BET is on Tesla HIGH NICKEL 4680 for Aircraft.
@Stewie Griffin the real stewie would just retrofit all airports with antimatter power generators and 50 cable power inputs for plane batteries.
That is awesome, I hope lifespan is still good, and charge and discharge rates are good as well.
Amazing!! 🎉 well done to those who did this!!
awesome Sandy thanks for letting us know about this much need battery improvement.
It certainly looks like Amprius has hit this out of the park. Kudos to them for keeping it quiet until they are going into actual production. Very nice reporting! All good wishes. P.S. I'm a very happy new subscriber!
a few questions: 1) $/kWh, 2) life cycle, 3) mass production?, 4) safety. Other than that, looks good :)
Thanks guys for the news.
pretty exciting stuff, I wouldnt be suprised if we start seeing 550+ mile EVs with large packs and much, much, cheaper and lighter 250+ mile EV's in the next couple years
That's what I expect within 3-5 year's from today. Top spec evs all over 500-600+ miles of rated range inc truck's and suvs.
Smaller segments are focused on affordability to go with small pack's and 220-270 miles of range but just 8-10mins charging.
The catl quilin pack claims up to 1000kms of range(cltc though so likely 800kms wltp and less for epa. Anyways what's astounding is a 70% charge of the 144.3kwh pack in 10mins. That's gonna take a 600kw charger and a sustained up to 6c charge rate. 😀👍🏻
@@4literv6 1000 Kms is 600 miles. Forget WLTP. EVs won't be 100% efficient so forget that range. 600KW charger isn't planned for with any EV charging infrastructure.
@@StephenShawCanada actually 480kw chargers exist in china since gac demonstrated them in summer 2021.
350+kw chargers have been widely available since 2021. 600kw Huawei chargers are going in right now in China further teslas v4 just started deploying in the EU at 1000v and over 600kw max. And the tesla semi takes 750kw right now from the Pepsi megachargers.
Nice try though you poor misinformed little troll. 👍🏻😎
More likely they'll use fewer cells to get the sane range and faster charge times.
Well, these cells arent likely to be the path to cheaper anything.
wow, that's some explosive news!
🤯
Hopefully not!
@@patreekotime4578 🤣🤣
I can't wait to hear more about this tech!
Looking forward to your deep dive when you visit Amprius!
Lots of unanswered questions: temperature sensitivity, cycle life, vibration resistance, end-of-life cost, charge/discharge rate, safety, manufacturing scalability, cost, for example. I wish them well in their roll-out.
and form factor
I thought someone else did the same thing but didn't tell anyone the cycle life sucked until their stocks went up. I think it was QuantumScape.
Hey you with the questions, you're harshing my vibe. Devil's always in the details.
@@banme2784 well that's the end of that. It was fun while it lasted.
I would be very interested in the:
- Price
- Cycle life
- and maybe power/charging speed (C - less important)
Pretty sure it's quite expensive for a battery pack and the silicon swelling would degrade the cells pretty fast. If they really have high cycle life with those "nano-tubes"... I bet it's gonna be very expensive for a long time..
Either way, always awesome for drones and all progress is great!!
Its hard to match lithium iron phosphate's 4000 charging cycles. I wonder if an independent lab has verified their claims.
@@greggmcclelland8430 It there a claim about Cycle life? I didn't hear it in this video.
@@TheKjelan 100 cycles ))))
SO, safety is not IMPORTANT ? you want USA jets Exploding mid air ?
I hope this can be used at scale. Thanks for sharing the good news!
Sounds great! It will be fascinating to watch this progress. 🙂
500 Wh/kg is a great news for Electric Aviation...the feasibility threshold is around 350-400...
Really interesting news. I hope they license their patent so hobbyists can buy mini versions of their battery.
That energy density is great but many have claimed to have a lot of energy density but they didn't have enough charge cycles.
Very exciting news! Curious to see how it plays out and whether we will see these in cars anytime soon. Look forward to your visit to the company.
Wow, great news, this will be a massive deal if they can nail mass production and maintain reliability.
IF stable for the breadth of temperatures and many many cycles, this would be great to get into Semis, Pickup Trucks, Heavy Construction vehicles, Massive boats, Snow Plows, Heavy Tanks, etc. So many applications. If they are just now building a facility in Colorado, then I am guessing this product is like 5 years away from mass production.
You can forget about semis. That is a non-starter for perfectly legitimate reasons.
@@artysanmobile There are already electric Semis in the marketplace and they are doing fine although some have very low range right now, but its early days and range, weight, and charging will improve as the technology matures/evolves.
@@strykerace re: "There are already electric Semis in the marketplace" indeed, but hold onto that thought cause in 1 years time I want you to count how many there are in operation...? and then in 3 years time I want to do another count how many there are in operation...? and then in 5 years time I want you to COUNT AGAIN how many there are in operation...? turns out, the passage of time has a way a forcing people to "bump up against the hard wall of reality". because: SOBRIETY.
Thank you, it is nice to hear you talk , and not say the same thing over, over, thanks
What a time to be alive ❤
Crazy that they managed to hit 100% silicon immediately instead of starting with a larger percentage of graphite anode. Hoping for good things from this in aerospace. And looking forward to the Lucid teardowns!
re: "looking forward to the Lucid teardowns!" which ironically has already been done by CEO Peter Rawlinson himself.
wonderful, i sincerely hope this comes to market. only problem is those of us who aren't "baby young to the world" (and thus coming into contact with these kinds of announcements for the first time) are forced to recall how we've already heard a constant stream of "battery breakthrough" stories basically at a rate of 2 per year for the PAST 20 YEARS. yeah despite being old, some of us DON'T FORGET so quickly and are able to REMEMBER a lot of these previous announcements - and to be honest - I'm not so sure if my great memory is a blessing or a curse in this regard. I mean I can remember back 30 years ago to when SUPER CONDUCTIVITY was all over the news.
I remember when I was a kid everyone in school kept saying how we're going to run out of oil in 50 years and there will be a Global international catastrophe... Now it 40 years later turns out we may never run out of oil because there will be alternatives that will be cheaper and easier and more environmentally friendly in the next 10-30 years - for everything except for aircraft... Like you, until it comes into production I'm going to basically ignore it...
Only thing is sandy n team has some credibility here to know what he is talking about, not pnly in terms of the underlying science, but also the practicality of legit production at scale
Exciting another insightful presentation
Good one, well done guys
Battery technology is evolving so fast… Something revolutionary every few months.
BIG OIL hate it....
Well, battery research is evolving quickly. Which is great. But what actually makes it into applications lags by 10 years or so... as it should.. we need to make sure batteries are safe and stable before putting them everywhere.
Problem is ramping to volume production. That's always the hard part and where most "breakthroughs" falter. This looks promising but I wouldn't get too excited yet.
It will be at the drone level where we see the improvements first.
In drones the battery weight is super important.
Much more than in cars
At 500 Wh/kg we also get several airplane options that become more viable on short haul routes up to 500km (300 mi)
Like flying regular routes to islands including mail runs.
Maritime long range patrol will be habilitated by this.
Never seen Sandy so excited
Wow, we finally get to see the innards of the Lucid and Hummer. I can't wait to see them.
Really Breaking News. Doubling the range is exactly what I would be looking for.
Why? Do you drive 500 miles between meals?
How often do people drive 800 miles NON-STOP?
@@mikafiltenborg7572 🤣👍👍
My last 2 gasoline vehicles had "ranges" of about 400-450 miles. The 2 before before that only got about 350 (I think gas tank sizes must have increased in the last 20 years because fuel economy was about the same on all of them). And unlike most of the armchair afficianados Ive actually timed myself taking rest stops on road trips. My average stop time for gas, snacks, and bathroom was about 30ish minutes... not the 5 minutes everyone SEEMS to think it takes. And at the minimum I have to stop for bathroom and snacks every 200 miles or so, and on longer road trips I get out and eat a sit down meal at least once. Theres a guy on TH-cam Bjorn Nyland who does 1000km road trips as fast as he can on just about every EV he can get a hold of, and for most of them he doesnt even eat a sit-down meal, usually he just chokes down a hotdog and hes off again.
And it seems HIGHLY UNLIKELY that anyone will ever ship an EV with a 800 mile range. From a general engineering perspective its better to reduce the overall vehicle weight. Lighter batteries means the vehicle needs less structure to HOLD the batteries, less structure to meet safety requirements, less beefy suspension, less beefy brakes, smaller and cheaper tires etc. So the overall weight of vehicles would be reduced far more than just the savings on the battery pack weight.
After taking several 2000 vacations in an EV, range is very important. Charge stations don't exist everywhere yet. Tried to go to Big Bend NP in Texas and actually couldn't because of range in our Y. Don't forget these cars are sold in other countries that don't have the infrastructure.
Love to know the charge rate, life span and any safety / stability info regarding the battery chemistry.
I knew this would happen, and I think many more had that feeling too. As soon as the need arises, things start to happen.
Fascinating and exciting! Remote tiny home living will become much more realistic when personal drones become practical IMO!
Mass production is where this will most likely snag as most of these "breakthroughs" do. But eventually, one of these new techs will break through and will have a significant impact.
but they seem closer to production than QS do they not?
That and how it ages.
@@pawpawbandit3871 and Enovix seems closer than Amprius. Who is first to market? Who knows better than Mr. Lithio
@@guidedbygreen1480 I'm betting it's Amprius but time will tell I guess; but probably not a lot of time - probably like a year or 18 months. The context clues and fact they're trying to build a plant asap, etc. I think they have a "real" producable, fly-able/ drivable battery. Also, the energy density is incredible, but seems realistic for the market for the near term, not like some company that was started last week and claims some incredible breakthrough
their website claims only the silicone anode is different. The rest of the battery is same old tech. So there is no insurmountable barrier into mass manufacturing
Very interesting, thanks.
Glad you enjoyed it!
Thats an impressive leap in power density looks like the Moore's Law applies to batteries now "doubling the energy density every two years."
Not so.
this is huge news for aviation ....HUGE / HOLY GRAIL HUGE
HUGE!!! congrats
Looking forward to the interview and their tech. Looking good for EVs, how much range would one get with potential half the number of cells ? The questions around efficiency will be interesting.
The simple answer is more range than you had. Every vehicle has a figure of merit. Long ago I had a GM EV 1 for every sixty pounds of weight added or subtracted I gained or lost 1 mile of range. The basic physics hasn’t changed It take energy to accelerate mass Force = Mass X Acceleration. Once the mass is at speed on a flat straight road with no wind The energy required is just the energy to overcome friction. EVs today consume between 200-400 watt hours of power. Cars on the lighter/smaller size require fewer watt hours per mile. Using really rough arithmetic The mass of the car might go down by 20%. Force required to accelerate will be 20% lower. Friction loses will go down, but not by the 20% that the force required for a given acceleration does. Rolling resistance and other loses dominate below 60 miles per hour air resistance dominates above 60 miles an hour. If the The vehicle size and shape is unchanged then the air resistance will be unchanged. So range will improve by something less than 20%
Thx guys
Thanks Sandy and Antonio for explaining some of the engineering details of Ampris' creation of a 500Wh/kg battery. Seem there will have to be a lot of testing and costing to see if it is commercially viable.
Thank you so much for letting us know of this awesome news!! It would be awesome to have 500+ mile range as an average for all EV's, not just one or two manufacturers.
No. That kind of range is just not needed in 90% of cases. Focus on small, compact, and light vehicles instead. 20KWh is PLENTY for typical daily usage. At that rate with this kind of density, EVs can actually be competitive with ICE vehicles on weight.
Prototypes are easy, this only counts if they able to make 100s of GWh a year and I think they're be suited well for electric planes only with few GWh a year factory.
If it provides a feasibility function the entire aerospace sector needs and they licence the formula/design out to a separate veteran manufacturer (like say LG chem or Panasonic corp.) they could own a large portion of the battery market for not only aerospace but also wheeled EVs without needing the heavy investment on their end for production to meet demand.
Well said.
appreciate Good Old Man for the breaking news; quite interesting
Sound like very good news!
Charge on!
Hope they do an LFP or LMFP version of these batteries for higher cycle life.
These are a different chemistry. Do you mean producing the same size and shape as 4680?
@@georgesackinger2002 I mean I hope they use coated nanowire silicon cathodes with Lithium Iron Phosphate (or Lithium Manganese Iron Phosphate) chemistry. This should increase their battery cycle life from around 1000 cycles (currently) to over 3000 cycles.
The big questions will be - how many times can it be cycled, and how fast can it be charged without damaging it. They would need to have figured out the problem of the silicon swelling when lithium atoms enter it.
Charging speeds should NOT be ramped up, the speeds these retarded chinese phone companies are doing is extremely unsafe and it blows my mind that samsung etc are following the trend
Electric Viking talked about this and Amprius about a year ago, seems like some good progress has been made over the past year.
Folks. It’s all about scaling, it takes time, and that’s the hardest part.
I really hope it is successful but some questions. Cost, number of Recharge Cycles, Recharge speed, safety ???
Be sure to talk to them about cost per KWH, rare earth element usage, exterior temperature performance, timeline for production, charge and discharge rates as it compares to current gen 2170 and 4680 among others like the Chinese batteries from BYD, CATL, etc
Also cycle life/degradation.
Did you watch? Did you listen?
You guys Rock ✌️
times are moving so fast, it's so exciting
Weight affects range so if the batteries have 2x energy density you would need a lot less than 50 % the mass of batteries to maintain an equivalent range.
no word on Formfactor Cylindrical, Prismatic or Pouch.
Reducing the battery cell weight by 50% will only decrease the vehicle weight by maybe 10-20% and increase the range by 5-10%, since the rolling resistance is usually only about 1/3-1/2 of the energy loss.
Weight doesn't have a big impact on range at the speeds cars travel. Rolling resistance is just a rounding error compared to wind resistance.
@@gasdive it's a big impact, it's probably roughly 10%; think about how big of an impact that is if you take 500M cars and drive them for 25 years
@@pawpawbandit3871 we can calculate that. A Model 3 pack weighs 450 kg. If batteries are 90% of the mass of the pack, that's 400 kg of batteries.
If you cut that in half, that's 200 kg.
Coefficient of rolling resistance for a good car tyre like the ones on electric cars is about 0.0062
200 kg x 9.8 is 1960N.
1960 x the CoRR 0.0062 = 12.152 N
12.52 x 1000 gives the energy used in 1 km
12152 J
Divide by 3600 to get Wh. That's 3.755 Wh per km. For comparison a Model 3 is rated at 165 Wh/km, so about 2.2% decrease in consumption.
The average driving distance in the USA is 13500 miles. Google tells me that's 21726 km. Multiply consumption by distance...
So that's 73,337 Wh, or 73 kWh. About 7 dollars worth of electricity at off peak rates, about 30 dollars at a supercharger. So if you charge at superchargers, and the car lasts 25 years, you could save 750 dollars.
500 million cars (a bit over a third of all cars on earth) would use 36 TWh per year. That's equal to about 90 minutes of world energy consumption.
Over 25 years that's 916 TWh. That's equal to just over a day and a half of world energy consumption over 25 years. Or a bit under 0.002% of world energy consumption. Not nothing. Not world changing. About like fitting wheel covers.
What kinds of cost are we talking about vs. other battery's?
Outstanding!
Munro the structure is called Villous - we have that in our intestines (Villi)
I would say the bigger deal here is the Amprius' claim of 80% charge in
It looks good in the video for sure, would love to see that tested on a "more than 1 test cell" level
Agreed...no point having 1000k range if it takes 24h...no car sits for 24h.
Good for ICE to EV conversions.
What I find surprising is that the 4680 battery ended up being a lower energy density than 2170s.
I thought the whole point of the 4680 was higher energy density+structural pack
The actual point of the 4680 = economics. It's really cheap per KWH & mass produced.
And the structural pack advantages are clearly not taken into account in these numbers.
The 4680 is also still in development, it is the first battery Tesla has ever made themselves... They have pulled silicon out of the cell to improve manufacturability and are slowly working on adding it back in
They are not considering the structural pack advantage (lowers the total weight of the car)
Not really. The cost and weight savings (from removing the separate floor structure of the vehicle) still make it a more attractive cell from a manufacturing standpoint, which is a very important metric when trying to scale to exponents of your current capacity. The 4680 is also still in its infancy, so I have hope that we see it becoming more and more energy dense over time as manufacturing techniques improve.
@@TheKjelan That is a very good point, thank you
Geniuses these 2! 😊
Battery improvements comming thick and fast now 😊
Can they make them at scale? And when?
And... 80% charge in less that 6 minutes! - according to the Amprius website. Is that possible?
6:05, i clocked it.
