摘　　要：研究一种利用本地区生产的高Nd混合稀土进行制作Co含量低于0.5的非包覆贮氢合金,发现其有易活化、此容量高等优点.采用合理的负极制造工艺后,该合金的性能在负极中同样可以得到充分发挥.以此制成的氢化物镍蓄电池可满足“高倍率型电池”的放电要求并具有较长的循环寿命.This report is about the research on performance of non-encapsulated MH alloy with high Nd and low Co content, the alloy is found to be with high discharge capacity and capable of being activated easily. Its excellent characteristics can also be showed in negative electrode if the negative electrode manufacturing process is improved. The Ni-MH battery using this alloy can be discharged at high rate and can endure long charge-discharge cycle.
