摘要	The La(2-x)Ti(x)MgNi(9) (x = 0.1, 0.2, 0.3, 0.4) alloys were prepared by magnetic levitation melting under Ar atmosphere. The effects of partial substitution Ti for La on the phase structures, hydrogen-storage proper-ties and electrochemical characteristics of the alloys were investigated systematically. For La(2-x)Ti(x)MgNi(9) (x = 0.1, 0.2, 0.3, 0.4) alloys, LaNi(5), LaNi(3) and LaMg(2)Ni(9) are the main phases, the maximum hydrogen-storage capacity is 1.51, 1.36, 1.35 and 1.22 wt%, respectively. The absorption-desorption plateau pressure of the alloys first decreases and then increases with increase of Ti content, and the La(1.8)MgTi(0.2)Ni(9) alloy has the lowest absorption-desorption plateau pressure. The discharge voltage of the alloy electrodes rises with increasing the amount of Ti content. The La(1.8)Ti(0.2)MgNi(9) alloy electrode presents good electrochemical performance.
