Sustaining an electrical charge difference across the poles of the cell by undergoing a chemical reaction.
For the common NMC batteries used in cars, I think the other metals start as oxides, which get reduced to oxidise the lithium.
In any case, I doubt that an inert atmosphere would help much.
A better approach might be to have high-capacity water pipes pre-plumbed to allow flood cooling of the affected cars. Possibly from underneath.
