英文摘要：

Since the carbon material has the advantage such as： cheapness, high specific capacitance and easy to produce. A carbon based electrode material was made via a optimized proportion of active carbon, carbon nano-tubes and MnO2.The results of cyclic voltammetry and alternate current impedance spectroscopy and charge-discharge demonstrate the capacitor made by the composite electrodes have large power density and energy density, and have perfect frequency and impedance characteristics for high-current charge and discharge. The capacitor still has an excellent circulation property after many cycles of charge-discharge. As a result this carbon based super-capacitor is a kind of good device for energy storage.
