摘要

对AB5型稀土系贮氢合金进行多元合金化降钴研究

在贮氢合金Ml（NiCoMnAl）4.5（CuFeCrZn）0.5-xVx的基础上

依次增加V（x=0.02

0.05

0.08）元素含量替代Co的方法制备加V低CoAB5型贮氢合金

并对其放电容量、循环稳定性以及微观结构进行了测试和分析。结果表明

可以获得综合电化学性能良好的加V低Co贮氢合金。但V的加入量应严格控制

在x=0.02的加V低Co贮氢合金具有较佳的综合电化学性能。

Abstract

Co-reduction in AB

type Re hydrogen storage alloy was conducted by a multi-element alloying method. Low Co-AB

type hydrogen storage alloy containing V can be prepared by substituting V （0.02

0.05

0.08） for Co based on M1（NiCoMnAl）

4.5 （CuFeCrZn） 0.5-xV

hydrogen storage alloy. The discharge capacity

cycling stability and microstructure of the alloy were measured. It is found that although low Co hydrogen storage alloy containing V has excellent comprehensive electro-chemical properties

V content should be controlled strictly below 0.08

where the alloy exhibits better comprehensive electro-chemical properties with 0.02% V content.
