Hydrogen absorption of nanostructural Mg₂Ni alloy prepared by mechanical grinding

Abstract

Mg₂Ni is one of the most promising hydrogen storage materials because of its high hydrogen absorption capacity. But its hydriding and dehydriding kinetics are very slow and hydriding/dehydriding temperature is very high. Recently much attention has been paid to make nanostructural Mg₂Ni alloy. The alloy is expected to have much faster kinetics for hydrogen absorption and desorption at lower temperatures. The hydrogen absorption properties of nanostructural Mg₂Ni alloy prepared by mechanical grinding is discussed.
