LaNi4.1Al0.3Mn0.4Si0.2Fex (x=0~0.4) hydrogen storage alloys were prepared by inductive melting. The crystal structure and phase composition of alloys were determined by XRD and SEM, and the electrochemical properties were also investigated. The results show that the alloys are composed of LaNi5 as main phase. When x≥0.1, some grey secondary phases are distributed on the main LaNi5 phase. With the increase of Fe content, the maximum discharge capacity decreases from 295.4 mAh/g (x=0) to 278.2 mAh/g (x=0.4), and the activity times increase from 10 to 18. Meanwhile the capacity retention rate increases from 66.85% (x=0) to 93.33% (x=0.4) after the charge/discharge cycle of 200 times.
