摘要：

Electrochemical characteristics of an amorphous MgNi alloy with Mg partially substituted by V were investigated. A Mg0.9V0.1Ni alloy prepared by mechanical alloying (MA) exhibited much better cycle life than MgNi alloy. It was found that the partial substitution of Mg in MgNi with V could suppress the formation of Mg(OH), on the alloy surface during the charge-discharge cycling in alkaline solution. This may have unveiled an important factor to improve cycle life of the Mg-based alloy for use in nickel-hydrogen batteries. (C) 1998 Elsevier Science S.A. All rights reserved.
