Polymer Gel Shows Promise For Smaller, Cheaper Batteries

The problem is that much electrical potential will NOT get rid of the "risk". if you short a high capacity battery no matter what it is made of, it will get really hot. they are not going to eliminate the burning battery syndrome. Better QC does that.

Internal resistance depends on the combination of battery chemistry and manufacturing technology. If you don't believe me, try shorting out comparable voltage / capacity ancient carbon zinc AA (good luck getting over a couple hundred mA, ask the model rocket guys from the 80s) vs a brand new Nicad (easily dump 50 amps, at least for a very short while, ask the RC car guys about melting connectors).

There is no inherent chemical or physical reason why you couldn't design/build a high internal resistance and h
