摘　　要：本文中,笔者研究了H^+浓度、Pb^(2+)浓度和放电电流对全沉积型铅酸液流电池的充放电性能影响。结果表明:在相同的充放电制度下,随着H^+浓度的增加,电池的平均电压效率增大,而平均容量效率和能量效率减小;Pb^(2+)浓度的影响呈相反的趋势;随着放电电流的增大,电池的平均容量效率逐渐增大,平均电压效率逐渐减小,但放电电流对容量效率的影响要大于电压效率,导致能量效率随放电电流的增大而增大。In the paper, the effects of discharge current, hydrogen and lead ion concentrations on the charge and discharge properties of lead acid flow battery were analyzed in detail. The results showed that the average voltage efficiency was increased and the average coulomb and energy efficiencies were decreased with increasing hydrogen ion concentration, whereas the influence of lead ion had the opposite trend. With the increase of discharge current, the average coulomb efficiency was increased gradually and the average voltage efficiency was decreased. The energy efficiency was increased because the influence of the discharge current on the coulomb efficiency was greater than that on the voltage efficiency.
