摘要：

The electrochemical properties of amorphous MgNi-based hydrogen storage alloys synthesized by ball milling were evaluated. In order to improve the cycle life, the surface of the amorphous Mg50Ni50 alloy was coated with Ti, Al and Zr by ball milling. Among them Ti was very effective to improve cycle life. And two kinds of MgNi-based amorphous alloys were designed by the substitution of Ti and other elements for Mg of MgNi-based alloys, which were composed of four components. Thus, the cycle life of electrodes with these quaternary amorphous alloys was strongly improved. (C) 1999 Elsevier Science S.A. All rights reserved.
