4680 cell tech specs

[canderous]

I'm working on writing an academic paper on the thermal management of Li-ion batteries for use in EVs, and I was thinking that running some simulations on the new 4680 cells would be a neat idea. Problem is, I'm struggling to find any sort of data sheets regarding specific thermal performance characteristics of these cells which are usually released by cell manufacturers, such as heat dissipation and discharge current curves, etc. Has this data simply not been released yet because they are still in development? Or am I just not looking in the right place?

Find which battery makers are working on 4680 and ask for spec sheets.
Panasonic? CATL? [Tesla doesn't make for re-sale only their own use - so will they publish specs??]
NorthVolt?
underdevelopment so it will take some research

I wouldn't expect Tesla to release those details for their 4680 cells, since they don't sell them to anyone. (So it is just internal information.)

Other people making 4680s might not be implementing all of Tesla's tech, so the specs probably wouldn't be the same. (Tabless, DBE, Tesla formulation, etc.)

Tesla patented the tabless design for the 4680, so AFAIK they are the only ones using it and aren't releasing specs.
You might search for the patent to see if there is info there.
