加V低Co-AB5型贮氢合金研究
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
5
type Re hydrogen storage alloy was conducted by a multi-element alloying method. Low Co-AB
5
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
x
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.
