Super-capacitor is a kind of electrochemical component, which stores energy by polarizing electrolyte without any chemical reactions. The process is reversible, which is the reason for super capacitor to be charged and discharged for about 100,000 times. Be as an energy storage device, super capacitor can store more energy than traditional capacitor and has the function of battery. It is widely used as power or back-power for LED, hand-set scanner, video, audio, CMOS, buzzer, toys, UPS etc.
