Abstract: Zr0.9Ti0.1(Ni,Co,Mn,V)(2.1) as-cast alloy was prepared by melting under Ar atmosphere; and then, four composite alloys were prepared by ball-milling after hydrogen absorbing agent was added. The initial discharge capacity was as high as 430 mAh .g(-1) for composite alloy electrode c discharged at 60 mA .g(-1) current density and its maximum capacity reached 505 mAh .g(-1). All composite alloy electrodes have good activation behavior, being fully activated in one or two cycles. At 300 mA .g(-1) current density, the composite alloy electrode c was found to have good cycle stability.
