Nice to read: Cobalt free nickel batteries are also coming. So LFP and NMX could compete with 1 another and without cobalt.
NM stands for Nickel Manganese, what is the 3rd letter X stand for.

Thanks Pedro.
Of the 3 main elements; Nickel, Cobalt, Manganese, if 1 is not available, can we use Lithium in the front as LNM just like LFP is for Lithium Ferrous Phosphate.
3 letter acronym should be simple and uniform.

Even for automobiles, this 3 letter wording can be used.

PEV: Plugin Electric Vehicle (Includes BEV & PHV, may include FEV if it has plug to charge a battery in future)
BEV: Battery Electric Vehicle
FEV: Fuelcell Electric Vehicle
PHV: Plugin Hybrid Vehicle (Escape, RAV-4 …)
FHV: Full Hybrid Vehicle (Prius hybrid, Ioniq hybrid …)
MHV: Mild Hybrid Vehicle (Jeep Wrangler, RAM 1500 …)
SHV: Stop/Start Hybrid Vehicle (Many models have this option)

Hi Pedro, i found interesting that this 115 Ah cell format is usable only for MEB battery packs with 12 modules = 77/82 kWh because the cell thickness allows to install 16 cells per MEB module. CALB already have prepared its own 113 Ah equivalent but also 78 Ah MEB compatible format which i think allow 24 cells in MEB module and so the 8 and 9 modules pack design is possible as well.

I wonder who will supply any type of battery cells to VW in china first 😉

Hi, why you not consider Blade battery of BYD?

Great. Next step, get rid of Nickel also.

This “inside the cell heater element” is very interesting. I feel like I’ve read about this before somewhere, but it’s possible it was tried with NCM batteries? Maybe LFP might be more suited to this idea.

It’s very interesting to see these things all come together, and how sometimes once the key elements are in place, the solutions are a re-thinking or a re-arrangement of existing pieces. Eg. Tesla’s 4680 cell and this LFP one, adding a simple heater element and controlling it with software.

Suddenly an LFP battery can charge very quickly and with limited degradation. If they are correct about this design, then a 70kwh battery should be able to charge safely to 80% < 15 minutes. I guess it'll depend on if the design is 400V or 800V and if the charger can deliver enough Amps.

Marcel, perhaps it was this 2018 paper (https://www.pnas.org/content/115/28/7266) by two of the three authors of this one? I can’t read the current article, but this 2018 one goes into a surprising amount of detail on how the in-cell heating foils work.

Interesting, thanks Bob. THat’s probably the one I was thinking of.

Also interesting that in the comments on that article they’re still arguing for swappable batteries. LOL.

Pedro were you able to get Sci-Hub to work on the paper cited in that article? I couldn’t, but based on the figures alone it looks to be fascinating.

Pedro, if you read the supplemental information section here: https://www.nature.com/articles/s41560-020-00757-7#Sec11 you’ll see YOU-PUSHEVS are cited several times in their paper! Interesting section regardless, but must be flattering to be cited by them. You might consider contacting the authors directly, as I’ve often been told paper authors are allowed to send you their own papers and since they’ve cited you, I’d say they take you seriously?

Primary objective is to get rid of Cobalt. After that the NMX : LFP should shrink from 2 : 1 to 1: 1.
From there intensive competition should continue to $100 / KWh threshold. Better to keep 2 chemistries. Any idea as what will be the 3rd chemistry.

Or something like this:
graphene-based battery combined with a 600A high-power charger, can be recharged to 80% capacity in 8 minutes! Vehicle model Aion V equipped with the new battery is scheduled to start production in Sep.” https://twitter.com/GAC_MOTOR/status/1354806440687505408
