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