一种改善贮氢电极合金电化学性能的新方法
, PP. 57-60
Keywords: 贮氢合金,氢化物电极,磁化处理
Abstract:
提出一种用以改善AB5型贮氢电极合金的综合电化学性能的新方法,即采用一定强度的外加磁场对电极进行磁化处理,以期提高电极合金的综合电化学性能.结果表明,外加磁场的磁化处理可以不同程度地改善磁体贮氢电极合金La0.9Sm0.1Ni5.0-yCoy(y=2.0,2.5,3.0)的电化学容量、循环寿命以及大电流放电能力等电化学性能.磁化处理对电极合金电化学性能的影响还与合金中的Co含量有关.合金中的Co含量增加,磁化处理后电极中存在的剩磁强度随之增强,磁化处理对电极合金电化学性能的影响也更为显著.
