>That said, put the battery pack in a gasket sealed steel case = snuffs any lithium fires by oxygen starvation for a worst case. Are you sure? I thought that one of the issues with lithium-ion fires was that the oxygen comes from the battery itself.

Yes, Lithium metal decomposes water used to quench into hydrogen and oxygen and combines with the oxygen = burns. There have been many cases of water fueled Tesla fires that have spurred the use of edge weighted fireproof blankets to starve a Tesla fire of air until it cools. Often special powders are use to the same effect - depends on each case, as different makers use different battery/anode/electrolyte combos. The higher energy ones = burn the best. https://www.firerescue1.com/firefighter-training/articles/tesla-on-fire-how-to-extinguish-an-electric-car-fire-n8dDvmqLHqggmoXr/ https://www.firerescue1.com/firefighter-training/articles/te...

  From what I understand the general idea is to lower the temeperature and keep it lower to prevent the reaction that prooduces the oxigen (and thus allow the burning and the re-ignition. The gasket sealed steel case may offer some sort of mechanical protection from the flames, and very likely allows to gain some time, but it seems not like it will prevent or extinguish the fire. And maybe there will be the need of a pressure relief valve, like those on pressure cookers to avoid the possible building inside of too much pressure, or possibly in case of fire the gasket will melt and let the case leak.
