You are right, but in the case of a Lithium battery fire the strategy is to use the large thermal capacity of water to cool the battery until the reaction is done.
I just remembered i can even name myself as a source when i fucked up and punctured my phone battery while disassembling it (those dumbasses used large amounts of adhesives to mount the battery and i wasn’t careful enough). I simply dropped it into a bucket of water and waited it out.
too much circlejerking with his neonazi buddies
