摘　　要：La-Mg-Ni系贮氢合金是新开发的大容量MH-Ni电池负极材料,但其市场化应用的瓶颈在于循环寿命太短。本文综述了改善La-Mg-Ni系(AB3-3.5型)贮氢合金循环寿命的方法,介绍了目前研究进展,讨论了La-Mg-Ni系贮氢合金的循环寿命与各种因素之间的关系,并对La-Mg-Ni系(AB3-3.5型)合金未来发展作了展望。La-Mg-Ni system hydrogen storage alloy is a new kind of MH-Ni battery negative material with high capacity, but its poor cycle life hinders its commercialization. We reviewed ways to improve the cycle life of the La-Mg-Ni system hydrogen storage alloys, introduced the current developing progress, discussed the relations between the cycle life of the alloys and the main determining factors and predicted the future development of the La-Mg-Ni system hydrogen storage alloys.
