Abstract: Researchers worldwide are in quest for developing newer energy storing devices as well as looking for improving existing devices in their performance. Demerit of capacitor is the low energy density and that for a battery is the low power density, these two difficulties are overcome by super capacitor which is the latest addition to energy storing devices. The present paper highlights on the differences between capacitor, battery and super capacitor, bringing out the ability of ultra-capacitor. The components of super-capacitor system are described in detail and focusing on the pros and cons of different material used for these components and their adoptability. The performance of the system is also dealt in detail with respect to energy density, power density, specific capacitance, self -discharge and cycle life.

Keywords: Super Capacitor, Energy Density, Power Density, Specific Capacitance, Cycle Life.
