Mg (NH2)(2)-2LiH system possesses a higher reversible hydrogen storage capacity and favorable thermodynamics, consequently being regarded as one of the most promising hydrogen storage materials. However, a temperature above 200 degrees C is needed to obtain quick de-/hydrogenation because of a rather high kinetic barrier. As a result, numerous investigations have been attempted to adjust the hydrogen storage thermodynamics and kinetics properties. Starting from the three aspects of material composites, nanocrystallization and modification by doping, the progress in the hydrogen storage thermodynamics and kinetics is systematically summarized in this review. The challenges and countermeasures are illustrated, and the direction to further enhancing the hydrogen storage properties of the Mg (NH2)(2)-2LiH system is also pointed out.
