采用电弧熔炼制备LaNi4.1Al0.3Mn0.4Si0.2Fex (x=0~0.4)储氢合金,借助XRD、SEM等分析LaNi4.1Al0.3Mn0.4Si0.2Fex合金的晶体结构和相组成,并研究合金的电化学性能.结果表明:合金主要由LaNi5单相组成,当x≥0.1时,在LaNi5主相上分布着些许灰色的第二相.随着LaNi4.1Al0.3Mn0.4Si0.2Fex(x=0~0.4)合金中Fe的加入量增加,合金最大放电容量由295.4 mAh/g (x=0)降低到278.2 mAh/g (x=0.4),活化次数也由10次增加到18次.同时合金200次循环后的容量保持率却由66.85% (x=0)提高到93.33% (x=0.4).
