La0.7Ce0.3Ni3.75Mn0.35Al0.15Cu0.75-xFex (x =0-0.20) hydrogen storage alloys are synthesized by induction melting and subsequent annealing treatment, and phase structure and electrochemical characteristics are investigated.All alloys consist of a single LaNi5 phase with CaCu5 structure, and the lattice constant a and the cell volume V of the LaNi5 phase increases with increasing x value.Maximum discharge capacity gradually decreases from 319.0 mAh/g (x =0) to 291.9 mAh/g (x =0.20) with the increase of x value.High-rate dischargeability at the discharge current density of 1200 mA/g decreases monotonically from 53.1% (x =0.00) to 44.2% (x =0.20).Cycling stability increases with increasing x from 0 to 0.20, which is mainly ascribed to the improvement of the pulverization resistance of the alloy electrodes.
