Hierarchically porous carbon (HPC)/MnO2 nanocomposites were fabricated for asymmetric supercapacitor applications. The microstructures of HPC/MnO2 nanocomposites were characterized by X-ray diffraction and scanning electron microscopy. The asymmetric supercapacitor consisting of a HPC/MnO2 cathode and a HPC anode shows an excellent performance with energy density and power density of 23.8 Wh kg-1 and 12.5 kW kg-1, respectively. In addition, the asymmetric supercapacitor exhibits an excellent cycle life with 91% retention of capacitance after 1000 cycles.
