> The material is decribed as highly responsive to temperature, with its electrical resistance increasing by 5,000 ohms (Ω) for every 1°C rise in temperature. The material’s maximum resistance is over 1,000 times higher than at normal temperatures, and it also features reversibility, meaning the resistance decreases and returns to its original state, allowing the current to flow normally again once the temperature drops.
To the best of my searching, a typical lithium ion battery has roughly 20-30 cathode-and-current-conductor layers. So naively this would add less than 50 microns to the battery thickness.

> high conductivity of SRL under standard battery operation
but I don’t know if the losses are truly negligible. I think we need someone who knows more about batteries.
It seems really promising, but if we up the cost of battery production and hence make them more expensive, then it would be nice to know it will still work after extended use.
