| Abstract: | Manganese dioxide(MnO2)/activated carbon(AC) composite for supercapacitor was synthesized by low temperature solid-state method.Effects of doping amount on the performance of the products were studied by XRD,SEM,cyclic voltammetry(CV) and galvanostatic charge-discharge tests.The diameter of the product was 1～10 μm.The optimum doping amount of AC was 7%.When charged-discharged at 0～0.8 V,the initial 100 mA/g specific discharge capacitance of the product was 375 F/g,the specific discharge capacitance in the 100 th cycle and 1 000 th cycle with 300 mA/g was 99 F/g and 74 F/g,respectively. |
