采用溶胶凝胶法，经过400℃煅烧的处理方式将氧化镍均匀负载在活性炭表面，通过XRD、扫描电镜、红外等表征手段对氧化镍/活性炭复合材料进行分析，并通过循环伏安测试对氧化镍/活性炭复合材料的电化学性能进行研究。结果表明：活性炭电极在负载氧化镍后，电容量提升了59．4％。对不同扫描速度下电极性能的差异分析显示：随着扫描速度的加快，复合电极材料的比容量有所减少。

Loading NiO nanopartide on activated carbon (AC )by sol-gel method,and using X-ray diffraction,scanning electron microscopy,infrared spectroscopy on this NiO/AC composite material characterization,the electrochemical performance of composite electrodes by cyclic voltammograms was studied.The results show that NiO/AC electrode capacity is 59.4% higher than the activated carbon electrode.The result of differences between different scanning speed of the electrode perform-ance shows that,with the increase of scanning speed,the specific capacity of the composite electrode material decreases.
