- čas přidán 2. 06. 2024
- What are the advantages and disadvantages of CALT LFP type batteries versus Tesla NCA type batteries what’s the basic science behind them? Today I’ll compare a standard LFP Chemistry like CATL’s to the NCA chemistry produced by Panasonic at Giga Nevada for Tesla to provide a Full Rundown of the Science and Specs.
For those looking for information on the BYD blade battery and Tesla’s 4680 with LFP, those will each be covered in separate videos. This video mainly focuses on chemistry, whereas the Blade and 4680 are mainly form factor changes that come with a host of additional benefits.

Fantastic video Jordan! No one can explain better than you in layman's terms. I hope everyone will realise how LFP will revolutionize the EV space and Grid storage. Specially for Grid storage with limited SoC window able to cycle 15k -20k cycles or 15-20 years lifetime.
Great information!
I think with limited SoC LFP could reach 30-50 years lifespan. No limits should easily make 12-15 years.
Looks realistic. I use an serie of 2.nd Life Winston 100Ah they have all 3150 to 3750 driving Cyles (SwissPostal Service) all above 82% and after another ~100 Cycles 20% to about 85% no additional Degradation Mesureable.
Wow this was one of your best videos, I feel like I really understand the difference now after watching this one.
Thanks Doug! One of my favorites too!
Yeah, agreed. Top notch content.
Most people won't take their cars to "end of life" (1 million miles). I think it's significant that LFP only degrades around 2-3% over the first couple of years of normal driving, while NCA typically degrades 10-12%. This is the difference people will notice.
Magnificent! As a solid state physicist I have to say this video is really well done and presented with great clarity!
That's a big relief! I was trying to simplify, but not so much that the technical detail was lost.
Jordan,
Have to say that I see your complete series becoming a valuable educational resource of many teachers.
(This is the first for a while where my head wasn't spinning at the end! 😉)
I hope so! I know if a couple teachers using them. It's shocking to me that this information isn't already public.
@@thelimitingfactor Just because it's public doesn't mean it's accessible, well formatted, and well presented. What you're doing adds real value - believe it! And thank you!
It makes me so happy that channels like this exist. I am so proud to be part of the hyper nerdy Tesla community lol.
Regarding thermal management there is one point to make:
LFP batteries require more energy to change the battery temperature because the LFP batteries are less energy-dense and therefore heavier.
Anecdotal evidence that I've heard suggests that supercharging preconditioning on the SR+ happens earlier and 30 minutes of preconditioning is not uncommon. (not helped by only one motor providing heat in the SR+ instead of 2 in the LR)
I think it might be due mostly to the 1 motor, since it’s half the energy so it would need double the time to heat the battery to the same temperature.
@@harsimranbansal5355 I'm comparing the SR+ variants, all have only one motor so it's a fair comparison
@@frederikjmx ohhhhh, sorry I misinterpreted that.
Wouldn't the heat pump negate some of the issue?
I've easily had pre-conditioning take 30 minutes or more minutes on my 2021 LR. Even when temps were above 50F. In the winter time, it takes even longer. I've had preconditioning start nearly an hour before arriving at a SC when it was only 15F outside. I wonder if it's even worse with LFP.
Great info put together you cant find anywhere else. Cant wait to see the coming LFP blade vs 4680!
Concerning the comparison with respect to range: NCA heavily degrades outside 10%-90%. Ideal range of operation is even 20%-80%. LFP can be operated in 0%-100%. If high DoD is a frequent occurrence in a given application, thats another advantage to account for on the LFP side.
That is accounted for in the cycle life numbers. The 800 - 1200 cycle life of NCA vs the 3000 - 4000 of LFP is based on a 0% to 100% charge/discharge cycle. If you use a 20 - 80% charge/discharge cycle for NCA, its cycle life will be similar to that of LFP @ 0 - 100%. So it's basically two different ways of saying the same thing.
@@CL-gq3no I do not think that you are correct and it was not done that way in this comparison (table near the middle of the video) as far as I can see. I get his and your point regarding the longer lasting range retention for LFP, but that was not my point. It would be unfair if the range would have been limited to a window of 20-80% in the case of NCA without saying so in aforementioned comparison. My point is: If you require a high DoD regularly, you will chew through the NCA a much faster. That is on top of the excess cycles that you get out of LFP. To rephrase it: If you change the DoD window, you change the range break even in the plot at the end and the areas that LFP is in advantage.
@@QuiddelQuaddel, The cycle life estimates for lithium batteries is pretty well known and it's based on the same testing standard in order to allow apples to apples comparison. NCA/NMC chemistries are good for ~3000 cycles if MOST of those cycles are in the 20 - 80% range. LFP cycles can be increased in the same way and may get ~5000 - 6000 cycles if MOST of it's life is spent in the 30 - 90% range. LFP is already being granted the higher cycle life, so downgrading NCA based on a 20 - 80% range when it is already being given a ~1000 cycle life based on a 0 - 100% profile would be downgrading it twice.
In practice none of this really matters that much because nobody consistently uses 100% DoD on a daily basis. Most people probably only use 10 to 50% daily and even on long road trips charging is usually in the 10 to 90% range (probably 15% to 88%'ish in reality since some of the battery is off limits). Therefore, in practice even the NCA batteries will likely be good for ~3000+ cycles and the LFP for ~5000+.
So for example, lets assume a user that is driving a lot more than average each day and has a standard range Tesla w/ NCA battery. So let's say a relatively high average DoD of 60% would get about 160 miles average for each cycle and about 3000 cycle life. 3000 x 160 miles per cycle is 480k miles. That is 20 years of driving 24k miles per year (twice the US average). The car will most likely be a rust bucket by then and it will have already lasted 2 to 3 times the average life of an ICE car. A long range Tesla would do even better as the average DoD per cycle would be even less. The LFP battery would be even better yet, but by now we are over a million miles which is probably well beyond the lifetime of the owner.
@@CL-gq3no Your understanding of cycles does not match what is common in the (cell) industry. The cycle life is defined as the number of full cycles (lower terminal voltage to upper and down again) at vendor specific conditions (C rates, temperature). I have just looked into a CALB NMC 58Ah datasheet because I had that at hand: Room temperature, multiple charge rates (1.2C CC 3.87V, 0.85C CC 4.1V, 0.33C CC 4.3V) and a discharge rate of 1C down to 2.75V. That yields > 2000 cycles for this type. This methodology is pretty common. You will see variations for e.g. more or less capable cells. I work with NCA/NMC, LTO and LFP.
@@QuiddelQuaddel, Ok, so you tell me then. How many cycles can we expect for something like Tesla's NCA 21700 chemistry under real world usage? So probably charging to 80 - 90% max most days, ~0.4C discharge rate, 0.1C charge rate most days, and an average DoD of ~30% or less. Graphs I have seen would indicate a lot more than 800 to 1200 cycles under those conditions.
Fantastic video, highly informative. there's one thing you missed though.
You talked quite extensively about cold weather performance but actually hot climate is very common and usually quite the issue for NCA.
LFP can withstand much higher ambient temps also the 3x cycle life helps in hot climates where degradation is more severe.
Besides that, excellent stuff
👏 Safety, $, long life make LFP the choice for mild climate with good Supercharger coverage.
I wonder how much better sodium ion would be.
LFP is definitely better for applications that don't require extreme energy density. for something like a truck or gosh even a VTOL, LFP is simply too big\heavy.
For the rest, LFP is superior with the exception of extreme cold climates.
For Tesla's mission the most important factor by a long shot seems to be total ICE vehicles kilometers displaced by EVs. In other words, the lifetime range of the battery. Easy win for LFP it seems
There it is! Got my snacks and beer ready... let's dive in!
I bought a new Model3 LFP in 2021, since I drive about 60.000km (37.000 miles) every year. I'm planning on keeping it until the end, hopefully 10 years, 600.000km (370.000 miles). The winters here in northen Europe gets really cold, but driving even in -25C (-13F) the M3 LFP works just great. I think salty roads and therefore corrosion we be the death of this car, not the battery ageing.
Hey Jordan, glad you liked our two videos on the Model 3 LFP type battery. For interested viewers, we have tons of charts and hand written subtitles in both: czcams.com/video/9N05pHUymtM/video.html
Tomorrow, we release a video that will probably again attract international attention.
Best regards from Germany,
Stefan
Bin schon sehr gespannt auf das Video morgen. Eagerly awaiting your new video tomorrow.
🤜🤛🤠
NextMove, best BEV channel in Germany!
Thanks as always Jordan. Please never stop 👊🏼
Thank you for delving into the details of the two battery chemistry, especially for me the numbers behind batteries fires - "oh I see why the can burst".
Keep up the good work.
Seriously the most underrated channel surrounding Tesla.
Thank you Jordan!
Fantastic stuff as always. With the LFP patent expiring, I expect to see factories in North America cranking them out at serious volume in the next couple years.
Fantastic video!!! I appreciate the hard work you put into this ❤️
Fantastic details, as always. Thank you for your hard work!
As a canadian, Im ok with your unholy mixing of units
🔥😂
I am very happy that he splits the video into chapters. Means I can skip all the boring stuff which I am not interested in because I'm not an engineer.
If I were a science teacher your videos would be required viewing for my class. I think it is so engaging and imagine more would enjoy these topics while in school if it was more "real life". Just imagine this will actual real objects and experiments etc in class for lab. We need to get kids excited about these topics. MATH and SCIENCE are too important too ignore especially in Public Schools.
Such a great talk. One of Jordan's best and simply the best treatment of this subject I've ever seen. Makes sense out of so many confusing counterclaims and data.
Again, speechless. Thank you so much for these videos!
Bravo Jordan! Perhaps my favorite video yet! You made the relationship between the chemistry at the molecular level and the real-world performance at the pack level so easy to visualize and understand. Outstanding work.
Very informative video, Jordan. Really looking forward to the deep video dives into the BYD Blade and Tesla 4680 form factors.
Magnificent and amazing way of illustration. Really Helpful. More power to you 👍
Absolutely incredible video once again. Possibly one of your best!
This video made me keep my standard Model 3 order with LFP battery. I was struggling with going with long range NCA version. Thank you.
hero. mindbogglingly good video with important information for everyone even vaguely interested in the EV space
Wow. You’re one heluva good explainer, Jordan!
I love your work.
I was designing a 2 wheeler EV for my our startup and this video really helped me decide the battery.
Cool to see the @nextmove reference here
Hello , just want to say that your videos are clear and straight to the point . Love those ! Thank you
You're most welcome!
Superb analysis, comparison, and contrast. Thank you!
Your information is absolutely the most comprehensive. Thanks for all your hard work.
My pleasure!
This vid doesnt only help me with tesla stock investment but also in choosing my next Tesla. Well done Jordan!
Always learn something from your videos. Thx for making it easy to understand.
Fantastic video.
I like it when the content is just a tad over my skill level and I have to struggle to keep up.
Awesome video! Answered a ton of questions about LFP chemistry.
Another fantastic video, Jordan!
What I like most is this reggae feel good intro. Well cut and welcoming as the content.
So a temporary small range penalty but a 3x product lifetime. Why would this be a difficult decision?
In all practicality a "long range" Model 3 only get you 40 mile more range if you keep a 90% state of charge during road trips. The time savings from a long range battery is better but not by that much. It really makes sense to stick with LFP batteries even when comparing between LFP and long range NCA battery packs.
The only real concern is cold weather performance. Heating that heavy pack up to sensible temperature is time consuming and energy hungry. If the climate crisis drives us into a new ice age then LFP is not so great, however...if we stick with Global Warming, then LFP should be fine...😉
@@rolandrohde . Climate change isn't so simple as your mind. In America, there is going to be extreme winter and extreme droughts of summer. You think you know more than credible scientists? Those 3% of scientists who don't agree are like the people who promoted the idea that cigarette smoke isn't dangerous to the body!
@@Moses_VII
I was making a joke...maybe I should have used "Irony" tags...🙄
Ask yourself if you need a 3x lifetime. A 300 mile NCA pack with 1000 cycles provides 300,000 miles. How much driving do you do and do you want to put money into fixing other parts of the vehicle with 300,000 miles of wear on them?
Great video, as always! watching from Brazil.
Thanks! Informative as usual!
Amazing video. Great presentation. Thank you!
Excellent video and summary!
Holy crap this video is gold. Excellent job! My opinions have been flipped.
Great info as always!
Thank you Jordan! Fantastic explanation! 🙏
This is one of the best presentations I have seen on CZcams.
Good voice, no distracting background “music” and very informative.
I know how difficult it is to obtain reliable data, so it is good that you sometimes mention “best guess”
As, without recycling worn-out batteries, there will not be enough mineable lithium in the world around 2050,
the problem of recycling lithium is becoming more prominent, and probably in favour of LFP because of its longer lifetime.
Thanks for your good work.
Thanks for the excellent explanation, Jordan. Bookmarked for future reference. You briefly touched on using LFP in 4680 cells. IMO this would mean Tesla could offer an SR+ and LR with LFP, and maybe a "super LR" with NCA. Exciting times!
Excellent video - you are an amazing teacher. Huge thanks
Big Love for your work, I just become a huge fan of you.
Huge thanks! Very well presented.
Fantastic video mate!
Very high quality video, thanks !
Once again an excellent video. Thankyou.
Tyres might see a little more wear on an LFP car. Brakes wear is likely to be the same, because the additional momentum gets fed back under regenerative braking
Great video, thank you. I’m brand new to the EV world. Just bought a model 3 with LFP last weekend. At this point, I’m very happy about my decision to go with LFP. I live in a warm climate so it made my decision a little easier. Very interested to see how well it performs over time.
Another excellent video. I'm starting to think I'd rather have an lfp standard range as over time it will lose less range. I would like an extra 20miles though. 270 miles just seems like a lot more than 250.
Can you not use more of the LFP battery though? 100% as opposed to 90% for NCA? This levels up the range somewhat.
I have an LFP model 3 and I’ve never had a problem (but that’s mainly because superchargers are so widespread where I live). Honestly just leave the battery display in % and you never really need to worry. For daily driving, it’s a complete non-issue.
Excellent video as always! You create the best technical content on batteries by far that I've seen! You mention cost not being any better due to shipping LFP from China. I suspect that will change by 2025 or so, since the patents are expiring next year and Lithium Werks is already planning large-scale LFP cathode production Stateside. I think it's only a matter of time before localized production brings the costs down substantially.
Excellent video. Thank you!
amazing explainations! eye opening to me ! thanks a lot!
Jordan is the GoTo Source to understand the State of the Art battery design and production. Great work.
Really great Work - thank you so much!
That's amazing fantastic one. Just waiting for the revolutionary most promising BYD's blade battery episode.
@@admin8187 Yes already done. Thank you Sir.
Tis is great information also helps understand cold weather issues an WHY a scheduled departure time makes such a big difference in cold weather.
As always, many thanks Jordan.
I like to factor in the effect on range of other factors... NCA will degrade faster if charged outside of the 15%-80% range, whereas LFP can happily go to 100%, but I like to factor in a reserve at the bottom of the LFP battery of 15%, mostly for the less predictable point at which the car will percieve the remaining capacity to be low (because of that flat voltage curve). So the practical capacity of NCA gets 20% off the top, and 15% off the bottom (so only 65% of the total charge being available if you want to look after the battery), whereas the LFP only gets trimmed to 85% of available capacity. Once these factors get applied the LFP SR+ has way more 'practical range' than the M3 NCA, and is almost of similar 'practical' range to the LR M3.
This was a phenomenal video. I see why NCA has been so appealing over the years due to the superior up front performance and immature LFP cell technology. After seeing this, I can clearly see how NCA can and will still have a niche market, but how LFP will become the new all purpose solution.
Worth mentioning, you outline how LFP doesn't show cost savings unless localized. I think this is important to note because 1) it already is localized in China, probably helping drive their margins higher, and 2) it will be localized in Texas and Berlin soon. What a time to be alive
Excellent as always. With lithium demand growing… an interesting topic could be the amount of lithium that goes into each chemistry. From LFP to LMNO and everything in between. Thanks. Love your channel!
Same amount in each chemistry. Everything in the battery cell is dead weight except for the lithium.
Thanks! Best chemistry video I have seen. Had been hearing about the safety of LFP vs NCA but this is the first time I have seen details. Personally, I would prefer a Hyundai or Subaru at this time. I am currently a Crosstrek owner and my litmus test is being able to carry an 8 ft ladder inside the cabin. Thanks for the great info.
Not only *can* you charge LFP to 100%, you *should* charge to 100%. This is because the voltage difference between fully charged and fully discharged is small and sometimes the BMS has a hard time distinguishing between the two. The effect would be that your range will drop precipitously when the battery state of charge gets low.
That would be another deep dive video idea; going into details about how often LFP charging to 100% is needed, why charging LFP to 100% & what happens inside the battery and BMS (battery management system) that necessitates 100% charging
you deserve an award for this video.
Very helpful analysis. Thanks!
Great video Jordan! I work in the LFP industry and I couldn't have been able to explain better ! LFP is there to stay because of the cheap price of raw materials used to synthetize it and the high cyclability of batteries made with that cathode material. Now, just to give you a slight insight: there are now some LFP manufacturers around the world that can synthetize LFP from steel mill wastes? On the long run, it might make it even cheaper than it was expected.
really good video - thanks
On point as Always!
Excellent video.
Great Segment
This Video convinced me to buy a Tesla Model 3 SR+ in 09/2021.
I was impressed by the LFP battery, how it works and especially his predicted long life.
🙌🏼🤠
My favorite video drop on youtube!
amazing work, thanks
That's a fascinating and really useful deep dive. Could you look into the impact of using LIPO chemistry in the 4680 tabless cell? Presumably the charging rate would be greatly improved by the lower internal resistance and even spreading of the charge throughout the cell.
It would also be interesting to hear your take on the range and life issues of using the different chemistries in the Tesla Semi.
Lipo isn't a chemistry, it just means using gel instead of liquid electrolyte.
Good questions.
jordan you really pack a lot of information in such a short time. I hope I can get LFP on my roadster for less problems. Hopefully I get a choice
Awesome battery chemistry video
Thank you for a very interesting and educational video;-) As allways👍
Very informative. Thanks.
Thanks for watching!
Extremely well researched video! This video has made me dump NCA because
1) I thought that LFP has terrible charging rates. But charging rates are at par with those of NCA batteries.
2) I hadn't considered that LFP would not only last atleast 5x longer than NCA but also have longer range than NCA for most of its lifetime.
3) LFP batteries prefer to be charged upto 100%
4) there is nothing stopping improvements in LFP batteries in future with silicon/DBE technology.
Sadly Tesla isn't manufacturing those.
... but probably will be soon.
I used an LFP engine start battery on a 1200cc BMW boxer twin. It replaced a serviceable (very heavy duty) lead acid because I could not use a conditioning charger while the bike was stored. Lead acid hates disuse. LFP doesn’t care.
The 4 AH LFP started that big twin better than the 14 AH lead acid ever had. It was also cheaper than s replacement lead acid.
I tried it on the car which has electric power steering (high power demand) and it worked just fine. I was not brave enough to leave the LFP on the car but believe it would have been just fine. The car is fitted with a 50 AH lead acid.
Very good and informative video. I wonder if the tables could be improved with the order of the columns since LFP is comparing with NCA from the left side of some tables but then from the right side on other tables.
Great video!
Thank you of making the video. I got 1.5kwh lfp batterys in my bike now and Over 2000w. Best thing is that power won't drop when charge gets low. Gas mopeds don't have any chance to keep up whit my bike.
Thank you Professor L. Factor)))
OK this makes so much more sense now. That is the reason why you charge NCAs from 20-80%, so the pillars are there, and I guess at the top level so the Li ions don't start pushing the layers apart.
Thanks for the video! Very happy with my Tesla Model 3 SR+ LFP here. :) By the way: Tesla increased the charge rate at the end - at 90% I get now still 52kW - that is much better than at the chart shown at 26:45 . LFP is charging really fast!
Niiiice!
Great video - clarifies lots of my questions on Battery chemistries. Thx again.
PS: can you also do a video on Lithium Air and Lithium Aluminium batteries please? I know they are unstable but i also hear about their fascinating gravimetric densities and i hope some day they iron out the kinks and it comes to fruition.
Again an excellent video, well done and very educational! Just for information sake, the Corolla started to be manufactured in 1966 not 1996.
