摘　　要：将碳纸与氧化还原反应法制备的纳米MnO2通过液相沉积法形成新的复合电极材料,采用循环伏安和交流阻抗测试技术对复合电极材料进行电化学分析,研究结果表明:碳纸/纳米MnO2复合电极材料呈花瓣状开放结构,有利于提高复合电极的比表面积;碳纸基体沉积时间为1h时,复合电极的电化学性能最稳定;但随着扫描速率的增加,复合电极的比电容呈下降趋势,且沉积时间越长,复合电极电容性的稳定也越差。The carbon paper and nano MnO2 by liquid phase deposition to form a new composite electrode materials,then using cyclic voltammograms and AC Impedance technology to test and analysis of composite electrode materials.Finally the results indicated that When the deposition time was equal to 1 hour,nano MnO2 film electrode prepared on carbon paper substrate was the most stable. When the deposition time was equal to 3 hours,the attenuation of specific capacitance was more than 50%,with the worst stability.Therefore,the deposition time was too long,which was not conducive to the stability of the electrode capacity.
