Abstract:

Mg(NH2)2-2LiH composite is one of the most promising high-capacity hydrogen storage materials developed in recent years. Research on Mg(NH2)2-2LiH material for hydrogen storage is of considerable interest because of its favorable thermodynamic properties, high reversible hydrogen capacity, relatively low operating temperatures, and good cycling stability for dehydrogenation/hydrogenation. In this review, the recent progress in the hydrogen storage properties of Mg(NH2)2-2LiH material was systematically summarized. The focus is on the effect of material composites, crystal structures, particle (grain) sizes, and catalysts on the hydrogen storage properties of the Mg(NH2)2-2LiH material, and their reaction mechanisms for hydrogen storage. The challenges in and direction for further improving the hydrogen storage properties of the Mg(NH2)2-2LiH material are also pointed out.

Key words: Amide, Hydride, Hydrogen storage property, Thermodynamics, Kinetics, Hydrogen storage mechanism
