摘要
综述了AB5型稀土贮氢合金高倍率放电性能的影响因素。从合金成分、制备工艺、粒度控制以及表面改性等几个方面进行总结 ,并对贮氢合金高倍率放电机制等问题进行了讨论。开发低钴无钴系列合金、非化学计量比、形成双相合金、控制粒度分布以及表面改性处理是目前改善AB5型稀土贮氢合金高倍率放电性能的有效途径。
A review was given on how to improve high-rate dischargeability of rare earth-based AB 5-type hydrogen-storage alloys. Several ways are valid for improving high-rate dischargeability of AB 5-type hydrogen-storage alloys, such as decreasing cobalt content, deviating stoichiometric proportion, adding some highly electrocatalytic materials, controlling particle-size, modifying surface, etc.
