Abstract
The electrochemical properties of amorphous MgNi-based hydrogen storage all oys synthesized by ball milling were evaluated. In order to improve the cyc le 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 sub stitution 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 Scienc e S.A. All rights reserved.
