英文摘要：
The present status and current developments of research on Mg-Ni-based hydrogen storage alloys are summarized. Mg-Ni-hased hydrogen storage alloys have the advantages of high hydrogen storage capacity, rich mineral sources and low material cost. The main factors that affect hydrogenstorage properties of Mg-Ni-based hydrogen storage alloys are briefly analysed. It is summarized that the use of techniques to make amorphous or nanocrystalline structure,partial substitution of foreign elements, and adding catalysts are highly effective methods of improving hydrogenation properties. Furthermore, the development orientation of Mg-Ni-based hydrogen storage alloys in the future is proposed. It is pointed that Mg-Ni-based hydrogen storage alloys are promising materials, hut to achieve practical application, there are still some issues for us to solve.
