I realize it's probably too soon to know, but what about safety? I think about the fact that hydrogen sulfide and sulfur dioxide are both toxic gases.

There doesn’t seem to be any elemental sulfur in these batteries, so how would those be formed? In other articles this chemistry is said to be much safer than Li-ion.

I'm thinking in a fire.

Common Li-ions contain fluoride (in separator and/or electrolyte additives, iirc). Which upon combustion produce HF and other nasties.

Compared to that, I'd rather take my chances with sulfur compounds.
