Abstract: Manganese oxide has been considered to be a promising electrode material for supercapacitors in
terms of its low cost, natural abundance, environmental friendliness and superior electrochemical performance. Characteristics and fabrications
of manganese oxide film electrode and powder electrode were discussed. Synthetic methods of preparing manganese oxide were summarized
systematically and the recent developments and main obstacles in the research of manganese oxide were reviewed. Moreover, the solutions to
improve the specific capacitance and electric conductivity by a doping and composite method were also discussed.

Key words: supercapacitor, manganese oxide, electrode material, synthetic method
