Hydrogen? It's evaporated solvents.

Well I stand corrected. I was always told it was hydrogen gas. Looks like that’s a myth propagated by earlier open-cell varieties that would vent hydrogen during normal operation.

What I do know from experience is that the gases smell like toothpaste. At least in the smaller lipo jelly roll packs

It used to be hydrogen when charging lead acid batteries, for example. NiMH also produces hydrogen once they are full, but that is internally converted back to water via a catalyst (hence they can be charged at 1/10 forever with only getting warm).

Not sure which chemistry would produce hydrogen during a thermal runaway event.
