摘　　要：根据复合贮氢合金的母体类型即AB5型稀土合金、AB2型Laves相合金、A2B或AB型Mg系合金、V基bcc固溶体型合金和La-Mg-Ni系新型合金,将Ni/MH电池复合贮氢合金负极材料分为相应的5种类型;综述了此类材料的制备方法、微观结构与电化学性能、分析表征方法及机制研究等,提出了目前研究中存在的问题与不足,并对该类材料的研究发展做了展望。The recent progress on study of composite hydrogen storage alloy as negative electrode of Ni/MH battery is reviewed, focusing on the major component, main methods of preparation, analysis and characteristic methods, micro-structural characteristics, electrochemical performance, and mechanism of hydriding and dehydriding. The composites are classified into five kinds based on the major component, e.g. AB5 type rare-earth hydride material, AB2 type hydride material with laves phase, A2B, AB type Mg-based hydride material, solid solution hydrogen storage alloy with BCC structure and new type La-Mg-Ni-based hydride material with stacked structure, respectively. The existing problems on research of the composite hydride materials are pointed out and the prospect of the composite development has been viewed.
