| 摘 要： | 对以ＡＢ２型合金为负极的ＭＨ－Ｎｉ电池的寿命进行了系统研究。采用封口化成工艺、负极为ＡＢ２型合金的ＭＨ－Ｎｉ电池在活化初期及大倍率充电时，由于ＡＢ２型合金较ＡＢ５型合金难活化及动力学性能差，内压更易升高，造成电池喷爬碱和微漏气，电池寿命变短。负极为ＡＢ２型合金的电池经过热处理，可显著改善电池寿命特性，为ＡＢ２型合金在ＭＨ－Ｎｉ电池中的应用提供了重要条件。

| Abstract: | The research on the cycle life characteristics of the sealed Ni MH battery using type AB 2 alloy as the negative electrodes was provided.uring initial activation and charging at high rate,Ni MH battery using seal formation results in much higher internal pressure,electrolyte and gas leakage,capacity degene ration,shorter cycle life,because of its more difficult formation and worse kinetic characteristics than type AB 5 alloy.It is reported that heat treated Ni MH battery using typy AB 2 alloy as the negative electrodes could improve its durability significantly,which is very important for the application of type AB 2 alloy in Ni MH battery. |
