Are kilowatt supercapacitors really a battery?
Kilowatt Labs, in their video above, refers to their supercapacitors as a pseudobattery and that is as good a name as any. It’s not a battery but it behaves like one as far as the user is concerned, except it is a hell of a lot more durable. Or at least we hope it is a hell of a lot more durable, since that’s its main selling point.
How much energy does a supercapacitor use?
(Image Source: Physicsworld.) While Arvio’s stated 46 watt-hours of energy per kilogram is excellent for a supercapacitor, it’s still not much better than a typical lead-acid battery and a module of lithium battery cells can store more than 3 times as much per kilogram.
