摘要
简述了镍氢电池负极材料AB5型贮氢合金A侧、B侧各元素对其电化学性能的影响。在此基础上,重点介绍了近年来国内外低Co、无Co贮氢合金在合金成分设计,制备工艺,热处理及表面处理方面的研究进展,阐明了低成本AB5型贮氢合金和镍氢动力电池发展的方向。
The effects on the electrochemical properties of AB(5)-type hydrogen storage alloys for Ni-MH batteries of adding elements to the A-side and the B-side are described. Advances in the worldwide development of low-Co or Co-free hydrogen storage alloys are reviewed. Considered are: component design, preparation technique, heat treatment and surface treatment. Prospects for the further development of low-cost hydrogen storage alloys and Ni-MH battery for electric vehicles (EVs) power are discussed.
