> Perhaps a different failure mode for the batteries; built-in extinguishers?

I hesitate to say 'it's not possible', but:

-Until a new battery formula becomes viable, we're pretty much stuck with batteries that light up when abused. Hopefully new formulas come online soon, but who knows wether or not they'll actually be safer.

-Chemical fires are pretty tough to extinguish via conventional means.
