摘　　要：采用循环伏安法研究了全钒离子液流电池正极溶液的浓度及添加剂对正极反应的影响。研究了两种离子交换膜对钒电池性能的影响。结果表明 :高浓度的钒离子溶液 ,其循环伏安表现不理想 ,而添加剂过氧化氢对还原过程有利。隔膜研究显示 :阳离子交换膜SelemionCMV有利于提高充放电电流和充电效率 ,但是机械强度较差 ,不利于长期使用。The effect of concentration and additive of vanadium ion redox flow battery on positive reaction was investigated by the means of cycle voltammetry. The results show that the high concentration of catholyte is unfavorable but the additive H 2O 2 is advantageous for reduction. The study on ion membrane shows that: using the cation membrane Selemion CMV increase the charging efficiency of battery, but it is too breakable to last a long period of time.
