Supercapacitors or electrochemical capacitors are an energy storage devices with many advantages including high power density, long cycle life (>100,000 cycles), faster charging/discharging rate compare with batteries, and environment friendly [carbon materials for chemical capacitive energy storage]. The supercapacitors are widely used in many applications such as consumer electronics, electric vehicles, industrial power and energy management [materials for electrochemical capacitors]. The supercapacitor consists of two electrodes with current collector which each electrode was separated by dielectric separator immersed in the electrolyte.
