Supercapacitor is an electrochemical energy storage device in the "power" industries Compared with battery, supercapacitor has one-tenth of energy, but delivers over 10 times power due to ultra low ESR. It operates more reliably in wider temperature and its life is semi-permanent, over 500,000 cycles.Main application: AMR, Actuator, UPS/DVR,Black Box, Wind mill Pitch control, Fuel Cell..etc
