摘　　要：以石墨烯(GP)为正极,MoO_2/石墨烯复合材料为负极组装有机系混合电容器,选定0.7~4.5 V为混合电容器的电压范围,对混合电容器的正负极质量比进行优化,实验结果表明,正负极质量比mGP/mMoO_2/GP为3.6时,电容器可以同时获得较高的能量密度和功率密度,表现出良好的整体性能。The organic hybrid capacitor based on graphene cathode and MoO2/graphene composites anode was assembled. The working voltage range was selected in the range of 0.7 to 4.5 V. By optimizing the mass ratio of the anode and cathode, the hybrid capacitor could obtain both higher energy density and power density at a mass ratio of 3.6（mGP/mMoO2/GP）. The optimized hybrid capacitor exhibits good electrochemical performance.
