Energy storage in capacitors

Energy storage in capacitors

A nice mathematical and practical comparison of Battery and Capacitor stored energy.

Super and ultra capacitors have a way to go.

A 3000F 2.7v from Electronic Goldmine can hold 10.94k Joules of energy: (1/2)*C*V^2

This is only equivalent to the energy stored in a .95Ah 3.2v Lithium Iron Phosphate (LiFeo4) Battery: V*Ah*3600.

Lets hope that Eestor are not vapor -ware.
