摘　　要：文章针对全钒氧化还原液流电池中存在的漏电电流进行了分析计算。在给出漏电电流计算方法的基础上,就充放电电流、电池串联组数和进液电阻及主管电阻等在不同的条件下对漏电电流的影响进行分析。结果表明:大电流充放电,漏电电流加大,但所占能量比减小;单电池串联组数减少会明显降低漏电电流,提高能量效率;提高进液电阻尤其是主管路电阻的阻值,可以降低漏电电流,提高能量效率。This paper analyzes and calculates the leaked current in the all-vanadium redox flow battery. On the basis of provided calculation method about leaked current, the paper mainly analyzes the influence about leaked current as the current charge-dis- charge, the number of series batteries and the resistance of vanadium solution. The results show that charge-discharge with high- current will increase leaked current and decrease the rate of total energy expenditure, leaked current will decreased obviously and en- ergy effciency will increase when the number of series batteries is reduced or the resistance of vanadium solution is improved.
