Tesla Single Crystal Cathode Patent (Deep Dive)
ฝัง
- เผยแพร่เมื่อ 28 พ.ค. 2024
- 12:58 for summary. This video is a technical deep dive and walkthrough of Teslas new 'NCA' patent. The patent is a methodology to create a high purity, high lithium, single crystal cathode material.
I explain what a single crystal cathode is and why the patent is actually a stalking horse for an NA 9505 cobalt free battery. I summarise with how the patent fits with my predictions for Battery Day, discussed how this opens up in house manufacturing for Tesla, and I reveal a new piece of information about Jeff Dahn's Sodium Difluorophosphate discovery (replacing the expensive Lithium Difluorophosphate).

Battery Day - “The most exciting day in the company’s history”
Agreed!
@@thelimitingfactor have you thought about collaborating with, 'All things EV' 'Hyperchange' 'TeslaDaily' and 'SolvingTheMoneyProblem' channels? You're the most underrated Tesla channel in my opinion and a bump in viewers from a collab would be great while bringing your valuable research to a wider audience.
@@Josh-cp4el I'm trying 🙏. No takers yet. I talk with the EV Stock channel a lot. Doing an interview with him today.
@@thelimitingfactor that's great, I watch all of Ivan's videos over at the EV Stock channel, great collab! I really enjoyed your other chats with him, that's how I found you in the first place!
@@Josh-cp4el Sweet!
You are the only person giving deep technical analysis of this stuff. Very clear and understandable. Thank you!
No problem Andrew! Glad it's found an audience and thanks for watching.
@@thelimitingfactor There's no shortage of surface-level analysis and fan/opinion vids. You're going into technical depth the way Solving the Money Problem and Hyperchange go into the financials. Great stuff man!
@@10kreviews2020 Thanks man! That's high praise.
@@10kreviews2020 No hate towards Steven or Gali but they don't even come close to this deep dive level
I never suspected batteries had so much room for improvement.
Apparently we let them be mediocre for way too long.
This is precisely the case. We're actually just starting to understand how they work. There are double the battery researchers there were 10 years ago and we have MUCH better tools for characterisation and modelling. I expect the next 20 years will be pretty amazing.
Batteries (lead acid) are what keeps nuclear submarines safe! But there are moves for newer battery tech to replace these.
@@derekjenkinson8014 Oh wow! Can you elaborate?
The Limiting Factor, basically the reactors are there for 100% duty. But things go wrong with C&I etc, so the submarine needs a back up power source. It isn’t diesels, as it’d need a bloody long mast to suck in air. It’s lead acid batteries 🔋, big ones and lots of them.

Oh and before anyone questions my knowledge, 28 years Royal Navy with 25 years on submarines, ending up as the head of the electrical departments.
Thanks Jordan ! Your brilliant hard work really helps nut bags like me... 🤯 and I also appreciate that you always have the honesty to go back and correct your mistakes. Please keep well.
LOL, yeah, I'm a nutbag too and it helps me to understand it when I have to work out how to explain it.
Thanks for the explanation. The clarity of presentation and analysis is much appreciated.
This is just amazing. It is great to be alive and witness it. Thank you for your explanation.
Great work. I don't pretend to understand the details, but I enjoy soaking up the concepts and their focus of technical advancement. Also, props for using the corrected slide on .1v impact so that viewers who had seen the first but not the second could still track that conversion. Keep it up!
Good to hear! Was hoping I didn't lose people in the depths, lol
Dear Jordan,
I just discovered your channel and I was blown away! Thank you so much on such an understandable explanation.
No problem Milos, thanks for watching!
Good job on the narration, animation and editing of the video, you deliver the information and I feel this barely restrained awe coming from you that really draws me in, and enhances the fanboy in me for these breakthroughs
Thanks man, much appreciated 🤜🤛
Absolutely stunning level of details in this video... Thanks. Look forward to see and try digest your other videos. BR, Per (Denmark)
I’m a simple man, I see a video about new tech, I click and like. 👌🏼
Glad to see this video posted :)
I appreciate that! Enjoy. Hopefully I didn't make this too in depth, lol
@@thelimitingfactor Not at all, it's what I look for from your channel. I really enjoy the in depth videos, wish that there was a channel that did the same for autopilot content speculation.
@@thelimitingfactor Depth is good, and so is your depth of research. It takes a deep understanding to explain complex subject matter in lay terms. I've got to watch this a couple of more times times to absorb/understand all of what you've said. What is your back ground Jordan? Thanks.
@@hughwaller6789 😁 I work in a tax department. Always loved science, but hated the classroom.
Its incredible how you were able to take such complicated info and explain it to us in such a easy to understand way.
Glad you think so! It was a lot of work to distill it down.
I'm so glad I subscribed to the limiting factor. You won't get this kind of detail anywhere else.
btw, the crystal borders are called "grain boundaries" in materials science.
Thank you! Helps my learning.
That is correct. Also x-ray (or any kind of wave) diffraction is based on a phenomenon called Bragg-diffraction, that is constructive interference of x-ray (wave) bouncing back from crystalline planes. That directly gives you the distance between two planes.
Crystals are mystifying. Make some room for more lithium ions!
Awesome, in-depth analyses! Would highly recommend you join forces with Sandy, as that may really complement both businesses
I'd love that. I have questions for that guy....
@@thelimitingfactor I'm sure he has a lot of questions for you too regarding the intricacies of Tesla's next gen battery chemistry. So - a match made in heaven. Do it! :-)
@@LarsPallesen Sandy works with a battery expert, Sean Mitchell interviewed him on his channel. The interview was nowhere near this detailed though.
After watching this, I feel like I can identify as an Alchemist. Love the “aha!” Moments in all the technical details. Gosh.
Totally! I enjoyed the aha moments when I was reading through it.
Look at this view/like and like/dislike ratio. I've never seen such numbers on TH-cam and you deserve it, Jordan.
Thanks Christoph!
@@thelimitingfactor Have you contacted Tesla Daily Podcast already? I'm sure Rob would love to have you on the show, and you'd have an excellent bump in viewership
@@entspannter_hase I haven't contacted Rob yet, one of the few people I haven't. I'll give it a crack!
Nice research, I appreciate the great info and efforts put in for this episode. Thanks :)
Thank you for the information. Great work! I appreciate the summary timestamp as well... you got my subscription for being a contributor with the audience's best interest in mind.
Time is our most valuable resource. 🙏
Jordon, I watched many of your videos. I have to say you are one smart cookie. I have a physics degree so it's nice to see someone who understands all the technical details and is able to explain it to the average person.
Thanks man! I try to understand. This stuff is just barely within reach of my IQ, lol.
Really well done video. I'm so not an expert in this material, but you present in a way that is comprehensible.
I appreciate that!
Thanks very much for the detail in the concept and process. Really appreciate this information.
Excellent analysis in very understandable way! 👍🏼
Absolutely incredible video production really appreciate the technical insight
You're most welcome, thanks for the support!
Man I could watch this type of videos all day!
I subbed to this after the first 30 seconds your descriptions and detail is fantastic! Happy I found this channel 👍
Thanks Mark!
Appreciate the deep dives. I’ve never seen a patent or crystal lithography explained do well.
The reason all BMSs support 5v is historical- 5v is the original semiconductor voltage dating back to TTL semiconductors in the 1970s. CMOS adopted the standard for compatibility, and it’s become the default unless you have a compelling reason to go to lower voltages (as CPUs often do.). So it would have cost more to make a BMS that didn’t support up to 5V batteries.... and it will cost significantly more (or require extra circuitry) to support higher then 5V batteries. 5V is the standard for integrated circuits like 12v is the standard for car batteries.
HA! That is some awesome information man. I may use this in a future video.
Hey Jordan,
Just watched your guest appearance on the EV Stack Channel.
Great to see you deepdiving with no notes!
Looking forward to.more.
Thanks as always Roger!
WOW , I found you via algorithms ! I've been following the DIY guys that turn regular cars into drag cars via electric motors with batteries and telling my friends that when battery of today take a big leap forward in technology the game is going to change big time ! Very informative , well done Sir , I subbed and liked and also hit the bell ,I'm going to get some popcorn ,this is going to be good LOL !
Thanks for going through this. Must have been a bunch of work to tease out all the details. Right down the rabbit hole after them.
You're most welcome! Yeah, I can't imagine be a patent officer. It would take a special type of person, lol.
Another thorough and well presented video! Thanks
Thank you again, I feel smarter having watched every video in your series.
Awesome. I'm trying to provide a good dose of knowledge with the 'news'
Brilliant stuff again Jordan. Fantastic, knowledgeable and very exciting stuff. As I sit here a car is revving their engine outside and the smell of diesel fumes enters the house and permeates the atmosphere. Cannot wait until Roadrunner is up and running and the ICE becomes a footnote in history.
Yeah man, I live in the city and when I smell the fumes it's a stomach turner.
I feel smarter already! Keep up the amazing work sir!
Thx for the timestamp. Very detailed video. Nice explanation too.
Even the most pro-TSLA bears like Hyperchange are underestimating the future of energy storage. Tesla is a battery company, which is using cars as a proof of concept and to fund progress to escape the competition.
Top notch video as always. The best battery youtube channel out there.
Did you mean Pro Tesla Bulls?
Bulls you mean
The limiting Factor!!! Seeking to transcend what limits us from doing whatever we can imagine Is In my opinion an Awesome way to advance all areas of human progress. Your ability to explain the tech in this area is hugely appreciated! So... NEW SUB!
Thanks Mel!
Interesting stuff as always!
Wow. Very informative. I'll share the whole channel to my Tesla contacts.
Thanks Nacho! Glad you enjoyed it.
My god, thank you for existing. These videos are great!
Glad you like them! 😃
You've earned my subscription, very well explained. Thank you.
Thanks for the support Eric!
Nice work as usual, I missed the notation in the patent regarding cobalt free applications.
Really appreciate your channel, no hype which I like
Very informative. Thank you for sharing.
WOW! Excellent, EXCITING information.
Very nice distillation.
I agree I loved the way this was presented very easy to understand. Thank you.

@@thelimitingfactor i work for a manufacturer who supply tools to the industry for battery creation, both vacuum deposition lines and atmospheric, so this is very interesting to me, both personally and professionally. would love to have Tesla as a customer :D
@@RobsRepairs Hey man, that's very cool! Good to know this type of video provides value. I'll do more like it as the opportunities come up.
Thank You. This is exciting. I never saw your channel before but I just watched you on Hyperchange. I'm subscribed to you now.
Nice! Thanks for stopping by 🙏
Hey Jordan, great content. I think a good idea would be to have a short ~10-15min recap video of the major points and your predictions about battery day to end this series right before battery day occurs. And Id also like to know if there is my speculation about what improvements they've made (it should make) to the pack design and what should we expect to hear there. Best regards
@thelimitingfactor if there is any* speculation..(or* should make)
Possibly! It's definitely a good idea, but I have to make a call on priorities. Did you watch the Terawatt scaling video? That covered advanced and basic cell to pack. There will be a series of interviews with the EV Stock Channel - did the first one today - just going through whatever questions Ivan has.
@@thelimitingfactor I did, I remember some things but I don't remember if you covered what the new pack design will be like, I will rewatch. And ofcourse yeah I understand. I just figure a lot of viewers might be like me and would really appreciate being able to watch a quicker recap video a few hours before battery day to refresh our memories because there are so many details in your battery day videos (which is what makes them great!). It'd be harder for viewers like me to sift through your battery day content to remember what did Jordan say the electrolyte would be? The cathode? The energy density? The pack design etc. And I figure it shouldn't take you too much time to make because no new research is needed, you've done it all already. So we get an easy way to refresh major points and you get easy views on a new video you've already done all the research for, just a thought!!
@@keithanacker1299 Totally! I can see the value.
👍 appreciate your content you're doing great!
Nice break down Sir
You're most welcome!
A nice step forward! Go team!
Excellent content 👍
What I would give to begin to slightly grasp your well prepared video, but I'm going to pretend I do. Keep up your excellent work. Can't wait till 3rd week of May!!! Tesla's stock is going to go up like a "Falcon Heavy"!!
LOL! Yeah, pretty dense information isn't it? That patent cooked my brain. Thanks for watching!
Awesome content thank you
I don't exactly remember if you already did this, but a video on the effects all this new inventions in the battery could do in terms of range for the different Tesla models would be nice, wouldn't it?
But great work as always!
Not enough time before battery day sadly! Also, it depends on how big Tesla want their margins to be.
Hi jordan, ultimate discussion about the single-crystal performance and the related patent description, however, the dQ/dV depends on the active material loading hence don't compare with a patent. since in the comparison dQ plot they have used pecific differential capacity value but in patent, they have displayed as obtained plot.
Thanks for this video and hats-off
Thank you!
Great video ty!
I'm watching your interview, and you mentioned an advanced way to do cell to pack while eliminating some steps in both the cell and pack production lines. This sounds very exciting, and it feels like the sort of leap Tesla would attempt. Can you talk more about this in a future video? Specifically, what steps they could eliminate and their impact on throughput? Thanks for reading this.
Thanks Brian! Yeah, pack weight savings are underrated! We'll see what pops up at battery day and go from there 🙏
Thank you!
When u make the next video, is there a way to put a moving mouse pointer on the screen as u walk through the technical graph and chart? It would be much much easier for us to understand and follow. Thank you!
Thank You ☺️
Thanks for another great video on this topic. The level of detail is much appreciated. One question though - am I correct in saying that you've effectively scaled back your expectations for the size of Tesla's battery improvement over time? A specific capacity at the cell level of 300 Wh/kg is good of course, but not quite as big a jump as you had expected earlier, right?
Good question. Expectations are the same - the 300wh/kg is the target for the cluster of improvements noted in this video. Further improvements such as Maxwell will stack on this 👍👍👍.
@@thelimitingfactor Ah, I see. Thanks for clearing that up. So you still believe a greater improvement will be announced at Battery Day then? As much as ... 350Wh/kg perhaps? ;-)
@@LarsPallesen Yes 😀. My hope is 320-330. Definitely want to see 300+ and their horizon for 350+
@@thelimitingfactor I think your 320-330 guess is right on the money. Those are my (optimistic) expectations too.
Well Done!
Excellent breakdown of the crystal structure patent Jordan! So excited for Battery Day. Did you hear on the Earnings call that Elon said Battery Day would hold the most important announcements in Tesla History??
YEAH! 🔥🔥🔥🔥🔥 So f----- excited. This is the day that the endgame is revealed.
I was wondering if you could do a summary video of the Tesla battery day videos. You have six videos, with a lot of information, including corrections. It would be terrific to have a summary video that goes over the expected targets and confidence, as well as summaries about how you expect the battery production process to change (video 3 I think had a terrific explanation). Something like: expected targets and confidence; new battery construction process, etc.
No detailed explanation needed, rather just an overview of all the predictions from all the videos in once nice package.
Hey Micha! I just ran a poll on this. What do I call my subscribers...hmmm...battery heads? Anyhow, they indicated that they'd rather see a video on Samsung's 'breakthrough' patent, so I put a supercut/summary on the back burner. The poll is in the community tab from my channel page.
@@thelimitingfactor sounds great. I think a summary video might even be better after battery day, because you will make that video anyway, and before each tesla reveal you put your summary prediction.
@@michapringle New patent just came out 😁 I may be focused on that now.
Thanks for this great content! Can you please share your thoughts about Nano One?
Looks like a good company, they just need to find a buyer for their products. That would require some market analysis... I'm more focused on battery analysis.
Thank you for this excellent video! great work as always. I am curious to what extent do you think Tesla will use the LFP cathode? I read that they are partnering with CATL to use LFP. It is cheaper than nickel-rich cathodes, but lower energy density. Grid storage? standard range M3?
I don't see why it can't be used for both. That's very much a question about Tesla's internal strategy, which is subject to internal constraints we aren't aware of. LFP is a solid chemistry. Very underrated.
@@thelimitingfactor Thank you. Yes I think Tesla will use both nickel-rich cathodes and LFP, especially in China where LFP is used with busses.
Does single crystal and titanium coating reduce heat generated during charge and discharge? This would allow faster charging and more power output.
Hmmm, I haven't seen that in the research. However, Maxwell's technology will do that :D
Brain fried today!
I'll watch tomorrow (UK)
No doubt I'll have something bto say 😁
Hopefully the video didn't do the brain frying, lol
@@thelimitingfactor
Having a "COVID moment".
Back refreshed tomorrow!
@@thelimitingfactor
I was wrong!
Nothing to say!
I think you have it covered
@@rogerstarkey5390 Thanks man! 🤜🤛
Thanks for the new video. Tesla has made a lot of their patents open for use. Is this patent also open for use?
You're welcome!
Are you going to do a live stream with commentary during battery day?
Yup! That's the intent 😃
Awesome!
Those slides showed much of the space between the crystals was filled. I wonder if that is the lithium ions? Damn impressive increase.
The single crystal may offer a slightly higher energy density, but it's mainly to increase durability and extend cycle life.
Jordan, just brilliant, Eamon Dublin Ireland
Thanks Eamon! Love your name btw. Irish have a monopoly on earthy/robust names I think.
I watched your whole video very interesting I understood 2/5 of it to be fair I'm a couple beers in during the pandemic
LOL. You did well my friend.
holly molly, thanks professor for the awsome science class, an real world application, thank you for breaking this down, I am a noob in science yet I enjoyed your content and liked the "details". Aare you on twitter?
Thanks for watching. Yup! twitter.com/LimitingThe
Well what we are seeing is the future of battery technology. This patent is the path to the future of battery development, and the technical death of the internal combustion engine.
Sure, but I can still buy 2 gas cars new to 1 tesla used, and my mechanic still hasn't gotten his electrictrician license.
Does this patent limit Nano One's value to Tesla, or does one process build on the other?
Btw, fantastic work. Your distillation of the meaning from these science papers provides a framework that makes them far more readable for lay people like myself. Thank you. Might I suggest adding links to the patents for those so inclined?
Nano One makes something similar. However, if Tesla manufactures in house, they might not need a company like Nano One. It depends of Tesla can scale this alone. Tesla seems to prefer that route.
When the pressure is off from battery day, I might start adding links :D
Great Video. Do you see NanoOne as competitor? Greetings from Germany!
Good question! It depends on how vertically integrated the other battery manufacturers become.
I never knew I wanted a single crystal cathode battery until now. I’m surprised it’s taken this long for a decent battery to be designed.
Straight up! Batteries are finally getting the attention they deserve by academia
I have the rare earth element that can be test for battery i tried heating it in high temperature it just glow in red and even if you put it to water while too hot it never breaks, my belief is that this kind of materials can be use as components of battery that is highly resistant to heat and a good conductor and energy storage...
Now all they need to do is introduce some kind of sound/wave propagation to control flow of electrons or atomic alignment.
Nice, super high tech. The Dq/Dv ratio are second order derivitives, using calculus, I believe. Hard core math.
Thanks for the info!
Amazing amount of work has gone into this video, thank you. If people are using this video for investment purposes. Maybe think about this. Tesla stock is a little expensive, so unlikely most wage slaves can afford to buy that many shares. I get that there are some very well off people, who can buy up large bundles, but I think everyone should be able to benifit from this technology revolution financially. So maybe apply a little lateral thinking to your investments? Lithium stock isn't that expensive (yet).
Dear Jordan,
How is this patent different from Nano One - One pot process?
You mention a 2 pot process. Does the patent discuss the 1st pot, and what it does?
Great illumination! This is really high tech stuff! Wish I had become a chemical engineer. This is cool stuff that I almost understood, despite being a JD. You didn't mention the filing date and how long it took to prosecute the patent. that would be the issue date minus the filing date. Wait; I see the filing date of Feb. 2019! That's way less than the typical 2 yr typical prosecution time! However it has priority date reference going back to Oct of 2018! This is wild fast patent prosecution. Maybe because no one at the patent office understands it? Is this an issued patent or just the publication of the application? What is the patent No?
Someone who works in the patent field just contacted me offering to help fill out my understanding of patents. It's just an application. If I do another one of these, I'll cover the type of information you are driving at above. Great points.
tyvm
@the limiting factor - Is this patent still in play for Tesla?
