摘要：
The hydrogen storage properties of LaNi3-type hydrogen storage alloys were investigated in order to increase the capacity of rechargeable nickel-metal hydride batteries. By partially substituting a foreign metal at Ni sites, the discharge capacity of La(Ni0.9M0.1)(3) (M = Al, Fe, Mn, Si, Sn, Cu) alloy electrodes could be increased at room temperature. In particular, La(Ni0.9Al0.1)(3) and La(Ni0.9Mn0.1)(3) alloy electrodes showed significantly higher hydrogen storage capacities and markedly better reversibilities than LaNi3. (C) 2003 Elsevier B.V.
