摘　　要：Ni-MH电池负极材料AB5型稀土系贮氢合金中A、B两侧各元素变化直接影响其微观组织和电化学性能。综述近年来AB5型贮氢合金两侧元素替代的研究进展以及各种合金元素与电化学性能之间的关系,旨在为开发新型高性能贮氢合金提供合金化思路。The changes of A and B elements have great effects on the electrochemical properties and microstructure for the rare-earth based ABs-type hydrogen storage alloy as the cathode material of Ni-MH batteries. The electrochemical properties of rare earth-based hydrogen storage alloy, and the substitution of A and B in the ABs-type hydrogen storage alloy are reviewed and the relationship of substituted elements and electrochemical properties are summarized in order to provide some ideas for researchers.
