摘　　要：测试了MH/Ni电池在大量过充情况下内压曲线 ,以及 1C循环寿命曲线。结果表明 ,内压对电池循环寿命影响很大。采用一种特殊工艺生产的贮氢合金有较好的催化活性 ,能显著地降低内压 。The curves of inner pressure under much overcharge and the curve of cycle life at 1C rate were measured at different charging current. The results indicated that the inner pressure of battery made much influence on cycle life of battery. The hydrogen storage alloy powders, which were treated specially, had a good catalytic activity.As the results inner pressure could be decreased,the cycle life of battery could be prolonged.

关 键 词：MH/NI电池 内压曲线 循环寿命
