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
