摘要：

As-cast Zr0.5Ti0.5(V0.25Mn0.15Ni0.6)(2) alloy with C14 Laves phase was ball-milled with nickel powders. Structure characterization and surface properties of the ball-milled powders were examined by using X-ray diffraction analysis and scanning electron microscopy. When the ball-milled alloy is used in a metal hydride electrode, it exhibits rapid activation, good high-rate discharge capacity and long cycle life, owing to the catalysis of the nickel-rich subsurface layer of the ball-milled alloy powders.
