The ions present in the electrolytes are adsorbed by the electrode material and, thus, a charge separation occurs, resulting in polarization at electrode electrolyte interface.

Capacitors are another class of energy storage device. Capacitors are passive two-terminal electrical components used to electrostatically store energy in an electric field. Unlike batteries, capacitors do not dissipate energy and employ non-faradic processes to store charge. Therefore, they achieve far longer life cycle and outstanding power
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.
