Lithium-Ion Battery Cell Chemistries
1. NMC Battery Cells
2. NCA Battery Cells
3. LCO Battery Cells
4. LFP Battery Cells
5. LTO Battery Cells
6. Energy Density
7. Battery Safety
8. Cell Thermal Performance
In this video, we discuss the different lithium-ion battery cell chemistries, including NMC, NCA, LCO (high capacity, high energy); LFP; and LTO. Erik Stafl draws a chart looking at cell voltages and depth of discharge to examine the differences in cell performance. NMC cells generally have a more defined voltage curve than an LFP cell, making it more difficult to estimate the state of charge on an LFP cell. LTO cells are generally lower voltage.
This video explores the trade offs between the cell chemistries, comparing energy density and cycle life, and where each chemistry may be the best fit. The safety difference is also important, and is inversely correlated to the energy density of the cell.
Temperature is the final topic discussed in this video, examining the temperature ranges at which each cell chemistry performs best.
This video is intended for viewers who want to understand more about lithium-ion battery technology, and how it may apply to a battery pack.

Dear sir, you are highly appreciated. Your body language, speech, tempo and analysis, explanation all are outstanding.
Very good content and in depth coverage of the subject, you have been able to condensed so much information in just in eight minutes. I have been watching so many videos on TH-cam where the creators will produce hour length videos but are unable to convey so much knowledge in so little time. Keep it up, wished this would kind of become a guideline for posting content on TH-cam.
great video as always. one thing to note is that NMC and LFP are for cathode, and LTO is for anode (to replace carbon). LTO still needs to pair with NMC or LFP
Thanks for the video, it was very interesting, now the differences between the battery types is much understandable, keep uploading such videos.
That's insightful. Thanks for the great presentation!
Thank you!
Very informative, thank you!
We are glad this video was helpful.
Such a great presentation!
Thanks for this very clear and pedagogic video !
Thanks for sharing this information.It is very helpful.
Thank you. Clear my explained
Great info and very well presented.
Very good video. Thank you!
I wish I had a teacher like him in college.!!!
I appreciate it so much😀
Great video!
Glad you enjoyed it! We have more videos coming!
Thanks for the insightful video Erik!
For an EV use case, fast charging capability is becoming a pre-requisite these days. From what I understand, Cobalt chemistries (NMC, NCA etc) and LTO cells are well suited for 2C and above charging rates, but not so much for the LFP cells. Most datasheets I have seen of LFP cells (CATL, CALB, EVE etc) have Continuous charging rates between (0.5-1C) and Max charging rate of 1.5C (I am guessing this for pulse charging from regen braking) in some instances. So, does this mean we can't have fast charging capabilities in LFP EV batteries?
Thank you sir....
Yes, that was very helpfull and interesting.
I bought some 30 lto-cells with 40A capacity each, but still have NO idea how to charge and discharge them right. What are the voltages to do the not harm them ??? ;-(
There are a few factors to consider when charging and discharging lithium-ion battery cells. Our best recommendation is to consult the literature that came with the cells and stay within these parameters. We are glad you enjoyed the video!
@@staflsystems thank you for your answer, there was not even one word sent with the batteries
bms and battery algorithms details if you can add
Lto is a different kind of anode while the rest are all cathodes.
Cathode is negative side not positive
