You are right about the energy density and limitations. I was more focused on the fast rate of storage and retrieval.

- therein 3y agoWe already have incredible supercapacitors. https://www.eaton.com/gb/en-gb/catalog/electronic-components/xl60-supercapacitor.html https://www.eaton.com/gb/en-gb/catalog/electronic-components... I have 4 at home and blows people's minds when you melt a wire with it. Incredible rapid current delivery.
- XorNot 3y agoThey don't store any meaningful amount of electricity (which is why they haven't supplanted Li-Ion batteries for power tools) and more importantly they have a cycle-life - they degrade from usage (source: my wife works for a supercapacitor manufacturer). You also get losses from practical usage - i.e. no one can build a 3V supercapacitor that has decent endurance (you can totally build one which will work, but you're rating it knowing that every cycle is damaging it).
