Abstract: Carbon coating MnO2 material (MnO2/C) was prepared by hydrothermal method and its supercapacitive behavior was studied in this paper. The structure and surface morphology of the MnO2/C were studied by X-ray diffraction patterns (XRD) and scanning electron microscopic (SEM) photographs. The capacitance and stability of this composite were investigated by cyclic voltammetry (CV) and constant current charge-discharge cycling (CD). The electrical conductivity and specific capacitance of MnO2 increase and its cycling stability improves after carbon coating.
