摘要: 应用循环伏安法研究石墨板、柔性石墨和PAN基碳布经双氧水处理又经热处理后在钒盐硫酸溶液中的电化学性能,并以处理过的上述电极组装成流动型钒电池.结果表明,电极经处理,其表面反应可逆性增强,峰电流增大,电化学性能明显得到提高.用处理过的石墨电极组装的钒电池其充电电流可达20 mA/cm2以上,放电电流达15 mA/cm2.扫描电镜显示,石墨电极经处理后表层结构发生改变,比表面积增大.

Abstract: In this paper,cyclic voltammetry has been used to study the electrochemical performance of the treated and untreated graphite,soft graphite and PAN-carbon cloth in vanadium sulfate solution.The results show that: the reversibility of reaction can be improved on the surface of treated electrode,and the current can also increase;the electrochemical performance of treated electrode is remarkably enhanced;in the process of charge/discharge,the charge current can reach up to 20 mA/cm~(2),and discharge current up to 15 mA/cm~(2);surface morphology of the treated and untreated graphite show that the treatment can change the surface structure of electrode and also add the reaction area.

Key words: Vanadium battery, Electrode, Cyclic voltammetry
