摘　　要：在铅蓄电池胶体电解液中加入SnSO4能够保持70次100%全充放容量不衰减。运用循环伏安法和交流阻抗法的电化学测试手段,对其反应机理进行研究,结果表明,胶体电解液中加入SnSO4增加了电化学反应面积,延长了电池循环寿命,减少了电池容量的下降。By adding SnS04 into the colloid electrolyte of VRLA batteries, the capacity can keep no attenuation after 70 cycles in full charge - discharge. In the work, the mechanism of the reaction was studied by using of the electrochemical test CV and EMS. It suggested that the addition of SnSO4 increased the reacting area, extended the battery cycle life and reduced its capacity attenuation.
