Abstract: Superlattice-type rare earth hydrogen storage alloys have been widely used in Ni-MH batteries, solid state hydrogen storage systems and hydrogen refueling stations based on their unique crystal structure and excellent hydrogen storage properties. However, with the complexity of application scenarios and diversification of performance requirements, some high-tech fields have put forward higher requirements for gas-solid hydrogen storage properties of superlattice-type rare earth hydrogen storage alloys. Therefore, the structure characteristics of superlattice-type rare earth hydrogen storage alloys and the current research status of gas-solid hydrogen storage properties were analyzed. The main methods for improving gas-solid hydrogen storage properties of superlattice-type rare earth hydrogen storage alloys were summarized, such as element substitution, annealing treatment. The effects of these methods on the structure and gas-solid hydrogen storage properties of superlattice-type rare earth hydrogen storage alloys were emphatically discussed. The future research direction of gas-solid hydrogen storage properties of superlattice-type rare earth hydrogen storage alloys was envisioned.

Key words: superlattice-type rare earth hydrogen storage alloys, crystal structure, gas-solid hydrogen storage properties, element substitution, annealing treatment
