Is Tesla using DRY Cell 4680's now?

[Leifmb]

So, there was a recent tragic crash involving a Cybertruck in California a few days ago on the 27th Nov. Anyway, it was reported that the vehicle was on fire and it was a pretty big blaze. However, according to the Piedmont Fire Department, the fire was EASILY extinguished. In a press conference, a reporter asked if the CT Battery was involved in the blaze and the Piedmont Fire Chief thought not because the fire was so easily extinguished. So, if the battery pack was damaged and did begin thermal runaway, causing such a large blazing fire, which is the easiest explanation of what caused the fire, how was the blaze extinguished so easily? My guess, the 4680's may be the DRY CELL version! From my understanding, the "usual" liquid electrolyte in NMC or similar batteries is flammable and contributes to massive fires in thermal events of automotive battery packs. Could Tesla have started using the new DRY CELL 4680's? I think its a possibility if the reporting is accurate. What do you guys think?

I don't think Dry cells avoid liquid electrolyte. If that was true it would be called semi solid state or solid state. Liquid electrolyte itself is not terrible alone... it just is flexible and allows the anode and cathode to short (my understanding) to cause the thermal runaway.

Elon said months ago that ALL Cybertrucks would have the dry batteries by the end of the year (2024). My SC was going to check and let me know but did not. Anybody ?

If the dry 4680’s don’t burn as bad OR can be extinguished easily-would be BIG deal!

The dry battery electrode process refers to the production of the electrodes. The cell itself still uses electrolyte.
The cathode has been the issue and should hopefully be finished with validation soon.
