摘　　要：采用正极预充电的方式降低金属氢化物-镍(MH/Ni)电池中负极放电储备容量并对其电池性能进行测试.结果表明,随着负极放电储备容量的降低,电池内阻下降,同时大电流放电后期电池电压下降,电池容量减少,但电池的循环寿命并没有降低.The discharge storage capacity of negative electrodes in metal-hydride-nickel （MH/Ni） batteries was decreased by pre-charge of positive electrodes, and the properties of the batteries were studied. The results show that with the decrease in the discharge storage capacity of negative electrodes, the internal resistance and discharge capacity at high rate of the batteries are decreased, but the cycle life rate of the batteries is maintained.
