For comparison, li-ion 18650-size 3500mAh cells are 260Wh/kg, that is almost +50% capacity per gram but only +15% capacity per volume
Still…
I understand that these things are perhaps less flammable because no electrolyte that burns, but also there’s a question about efficiency, manufacturability, overheating, charge depletion in time and across cycles etc. Maybe it’s not even any good
Drone batteries then
Only if power density is good enough
I’d have thought that the weight would be the deciding factor
