Abstract

MnO2 is directly deposited on active carbon (AC) to synthesize AC/MnO2 composite to improve the capacitance of electrode material. AC/MnO2 composites are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and N2 adsorption-desorption, and the electrochemical properties are evaluated by cyclic voltammetry (CV) and galvanostatic charge/discharge (GCD) test in 1M Na2SO4 aqueous solution. The results suggest that the AC/MnO2 composites show a double layer capacitive behavior in the potential window of -1~0 V. The specific capacitance of AC/MnO2 (250 F g-1 at current densities of 2A/g-1) is notably higher than that of AC (200 F g-1 at current densities of 2A/g-1).
