3. Electrochemical capacitor background. The concept of storing energy in the electric double layer that is formed at the interface between an electrolyte and a solid has been known since the 1800s.

A supercapacitor is like a hybrid of a battery and a standard capacitor. In other words, it can hold a greater electrical charge than a standard capacitor. Not only that, but a supercapacitor can handle more frequent cycles of charging and discharging stored energy. Battery VS Supercapacitor. Below are the main differences between a battery
The expression in Equation 8.4.2 8.4.2 for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference V = q/C V = q / C between its plates.
