Types and Preparation of Hydrogen Storage Alloys

贮氢合金应用领域广泛。本文介绍了金属贮氢合金的主要分类以及贮氢合金设计的基本要求 ,并且对贮氢合金制备方法进行了较为全面的总结陈述。目前已开发研究的贮氢合金主要有四类 ,其中最广泛研究应用的为AB5型稀土合金。贮氢合金的制备方法有很多种 ,如传统的熔炼法、机械合金法、燃烧合成法。

Hydrogen storage alloys have a wide application field. Here we introduced the main types of different hydrogen storage alloys and the basic rules of design of hydrogen storage materials. Also, we presented a detailed introduction on preparation methods of hydrogen storage alloys. Now, there are mainly four types of hydrogen storage alloys, among which AB 5-type (A = rare earth metal) has been the most widely studied and used. On preparation of hydrogen storage alloys, many methods such as conventional melting, mechanical alloying (MA), combustion synthesis, melting spinning and replacement-diffusion method etc. have been developed.
