A novel nano-composite of polyaniline/mesoporous carbon(PANI/CMK-3) was prepared with mesoporous carbon(CMK-3) serving as the support.Electrochemical asymmetric capacitors have been successfully designed by using PANI/CMK-3 composite and CMK-3 as positive and negative electrode,respectively.The results showed that the discharge capacity of the asymmetric capacitor could reach 87.4 F/g under the current density of 5 mA/cm~2 and cell voltage of 1.4 V.The energy density of the asymmetric capacitor was up to 23.8 Wh/kg with a power density of 206 W/kg.Furthermore,PANI/CMK-3-CMK-3 asymmetric capacitor using this PANI/CMK-3 nano-composite could be activated quickly and possess high charge-discharge efficiency.

These results showed that the discharge capacity of the asymmetric capacitor could reach 87.4 F / g under the current density of 5 mA / cm ~ 2 and the cell voltage of 1.4 V. The energy density of the asymmetric capacitor was up to 23.8 Wh / kg with a power density of 206 W / kg. Thermal Co., PANI / CMK-3-CMK-3 asymmetric capacitor using this PANI / CMK-3 nano- composite could be activated quickly and possess high charge- discharge efficiency.
