- S_A_P 8y agoI agree with you 100%- there should be a protocol for handling this situation. I have know idea what that should be, but seems like there needs to be a way to encapsulate the battery with an insulator and prevent any further shorts/fires.
- blattimwind 8y agoPutting the car in a large, fire-proof steel container (specialty engineering, they exist) for a few weeks (so you are at least somewhat sure it won't start catching fire RFN). Then dismantling the battery by hand, inspecting each cell individually. You can't really put anything around it (like a nitrogen atmosphere) that prevents fires, because the oxygen is already in there in the cathode. And so is the energy to ignite it.
- stephengillie 8y agoRemoving any heat source, to prevent further damage and lithium leakage, would seem to be priority. Pulling the battery fuse should be involved. A non-flammable chemical to make lithium inert would be ideal. Mineral oil or another oil could be poured into the exposed battery, but these could make the situation worse. Maybe lithium could have something else poured onto it, with the end-product of petalite (LiAl(Si2O5)2) or lithium chloride (LiCl).[0] The lithium could later be recovered from these molecules.
