摘要
综述了低成本稀土镍基AB5型贮氢合金的研究进展。分别从合金B侧元素、A侧元素、非化学计量比、制备方法等4个方面进行总结。综合考虑合金成本、成分和性能,可将低成本AB5型贮氢合金分为3类:低钴无钴低成本型、无钴低镍超低成本型、低钴含微量镁低成本高性能即高性价比型。开发低成本AB5型贮氢合金是贮氢合金研究的重要和可持续发展方向之一,相应低成本合金产品占有重要的市场份额。
Based on the influence of B-side or A-side elements substitution, non-stoichiometric ratio and preparation methods, the development of low-cost RE-Ni-base AB5-type hydrogen storage alloys was reviewed. Considering the raw materials cost, the chemical composition, and the performance of the low-cost ABs-type alloys, they can be classified as the low-cost-type, the super-low-cost-type and the high-cost-effective-type. It is important and eternal to develop low-cost AB5-type alloys, the sales volume of which takes up more than 50% of the total volume of hydrogen storage alloys in China
