If it is nonflammable I wonder what its failure mode would be and how it could be triggered and what counter measures are needed if any.

If it has the energy bound within and accessible there must be some way to release it and some would be faster than others.

I would think that it can still short out and overheat, but the material the battery is made of does not combust or have any exothermic chemical reaction. The energetic failure mode would be- "sparks and gets really really hot."

This is the case for normal lithium-ion batteries as well; they perform better at 120°F than at 70°F (and lose significant performance at even lower temperatures).

Probably the only way of releasing the energy fast is to short the battery with a thick wire, or to burn the whole battery with an external source.

There's no rule that having lots of bound up energy has to be dangerous, that it has to be possible to release it quickly. There's enormous amount of potential energy in pure hydrogen gas. If you can just fuse the atoms. But it's incredibly hard to release it.

Cold weather performance is an issue for the folks who replace their motorcycle battery with a lithium ion aftermarket upgrade. https://advrider.com/f/threads/lithium-ion-batteries-in-cold...

I'd love to know what's wrong with the polymer electrolyte, the demo is so amazing..

I'll believe it when I can buy a cellphone with one. Miracle batteries are like Alzheimer's cures and memristor computers: they show promise in the lab but fall down hard when used to develop products people actually use.

Yep. You can bet that if a patent hasn't been filed the creators have no faith in the scalability of their invention.

Can't find any details myself but the usual issue is energy density or number of charge cycles.
