摘　　要：详细讨论了Co含量对MH Ni电池性能的若干影响 ,得出Co含量增加可改善AB5型贮氢合金的力学性能和热力学性能 ,但会造成AB5型贮氢合金动力学性能明显降低。因而 ,控制合金中Co的含量对改善MH Ni电池性能有着极其重要的意义。实践表明 ,在改变B侧组成的同时 ,调整A侧组成 ,即使合金中Co的用量降到 3 % 。Influence of cobalt content on Ni MH batteries was discussed in detail. Increase of cobalt content in the AB 5 type LaNi 5 based alloys improves its mechanical and thermodynamic properties, while its dynamic properties deteriorates obviously. As a result, the control of cobalt content in the alloy is extremely important for the improvement of properties of Ni MH batteries. Performance of hydrogen storage alloy can be improved by changing the compositions of both side A and side B, even the cobalt content in it is decreased to 3%.
