Abstract: Mg-Ni based alloy has always been paid much attention as important negative electrode materials for Ni/MH battery. Recent research progress in Mg-Ni based alloy by mechanical
alloying for Ni/MH battery hydride electrode materials was reviewed with its focus on the electrochemical performance, micro-structural
characteristics, mechanism of hydriding and dehydriding and the main methods in preparation and modification of Mg-Ni based alloy electrodes such as
Mg-Ni based binary alloys, ternary alloys, composite alloying and surface modifications. Also the main direction of studies on Mg-Ni based alloy by
mechanical alloying for Ni/MH battery negative electrode materials was proposed.

Key words: mechanical alloying, Mg-Ni based alloy, amorphous, nickel-metal hydride battery
