Among the solid-state hydrogen storage materials,Li-Mg-N-H system hydrogen storage materials are considered to be the most promising hydrogen storage materials due to their good thermodynamic properties,good reversibility and high theoretical hydrogen storage capacity.However,due to the poor kinetic properties of the Li-Mg-N-H system,the rapid hydrogen absorption and desorption reaction can only be carried out above 200℃.Therefore,the current research status of thermodynamic and kinetic regulation of hydrogen storage materials in Li-Mg-N-H system is reviewed in detail from three aspects of composition regulation,nanization and doping catalyst,and the future research direction is pointed out.
