贮氢合金作为一类新型的功能材料，在Ni/MH蓄电池中有着广泛的应用前景。本文综述了近几十年来为高能量和高功率MH/Ni电池开发的特殊合金族，特别是用于EV、HEV和PHEV应用的合金族。工作范围包括Ni/MH电池的原理、电化学储氢热力学和动力学、储氢电极合金的先决条件以及储氢电极合金的最新进展。重点介绍了稀土AB（5）型合金、Ti基和Zr基AB（2）型合金、Mg基非晶/纳米晶合金、稀土-Mg-Ni基合金和Ti-V基合金。最后指出了MH/Ni蓄电池用新型贮氢合金的研究方向。
Hydrogen storage alloys are of particular interest as a novel group in functional materials owing to their potential and practical applications in Ni/MH rechargeable batteries. This review is devoted to the specific alloy families developed for high-energy and high-power Ni/MH batteries in the last decades, especially for EV, HEV and PHEV applications. The scope of the work encompasses principles of Ni/MH batteries, electrochemical hydrogen storage thermodynamics and kinetics, prerequisites for hydrogen storage electrode alloys and recent advances in hydrogen storage electrode alloys. Rare earth AB(5)-type alloys, Ti- and Zr-based AB(2)-type alloys, Mg-based amorphous/nanocrystalline alloys, rare earth-Mg-Ni-based alloys and Ti-V-based alloys are highlighted. Additionally, the challenges met in developing advanced hydrogen storage alloys for Ni/MH rechargeable batteries are pointed out and some research directions are suggested.
