Abstract: Abstract：Rare earth-based hydrogen storage alloys are the first developed hydrogen storage alloys and the only hydrogen storage alloys applied in a large scale now. This review is devoted to review the progress in rare earth-based high performance hydrogen storage alloys. The preparation methods，such as induction melting，arc melting，vacuum magnetic levitation melting，and a novel method self-ignition combustion synthesis，are introduced. The modification treatment methods，such as heat treatment and surface treatment，are summarized. And the relevance between the composition and the performance of AB5-type and rare earth-Mg-Ni-based hydrogen storage alloys are discussed respectively.

Key words: rare earth-based hydrogen storage alloys, anode materials, Ni/MH batteries

摘要： 稀土储氢合金是研究最早的储氢合金，也是目前仅有大规模产业化的储氢合金。本文综述了近年来稀土储氢合金的研究进展。介绍了稀土储氢合金的主要制备方法，例如感应熔炼、电弧熔炼、真空磁悬浮熔炼等以及较为新颖的自燃燃烧法；总结了改性处理方法，如热处理、表面处理等；分别讨论了AB5型、R-Mg-Ni系稀土储氢合金的元素组成变化对合金性能的影响。
