Summary: Energy storage is crucial for the large-scale utilization of renewable energy. Magnesium hydride (MgH2) has the advantages of low cost, abundant resources, and high energy storage capacity, but its practical application is hindered by sluggish kinetics and poor cycling stability. This review summarizes recent advances in enhancing the hydrogen storage, lithium-ion storage, and heat storage performances of MgH2, and discusses its prospects in these fields. It is expected that this review will inspire insightful and pioneering research on the design and preparation of MgH2 with excellent energy storage performances.

Summary: This study employed TiNbAlC MAX material without corrosive HF solution to improve the hydrogen storage performance of MgH2. The MgH2 + 10 wt% TiNbAlC composite was prepared by ball milling. The addition of 10 wt% TiNbAlC significantly reduced the onset temperature of MgH2 desorption and improved the hydrogen absorption capacity of MgH2 at room temperature under high H2 pressure. This work provides new insights into the role of MAX phase in tailoring the hydrogen storage of Mg-based materials.

Summary: Whether it is fossil energy or renewable energy, the storage, efficient use, and multi-application of energy largely depend on the research and preparation of high-performance materials. Mg-based materials have demonstrated potential industrial applications as large-scale hydrogen storage materials, but they also have certain disadvantages. This article reviews the surface modification methods and mechanisms for Mg-based materials in hydrogen storage and Ni-MH battery applications, and highlights the significant improvements in energy storage performance and material properties achieved through surface modifications.

Summary: The configuration of phase change materials in hydrogen storage tanks affects the storage performance. Sandwiched MH-PCM units have faster heat transfer and reaction rates due to larger transfer area and smaller thermal resistance. The amount of PCM affects the reaction fraction and can slightly impact absorption and desorption rates when reduced within sufficient limits.

Summary: In this study, MoS2 catalyst was synthesized via a one-step hydrothermal method, and its catalytic effect on the hydrogen storage properties of MgH2 was systematically investigated. It was found that MoS2 could significantly enhance the hydrogen release and absorption rates of MgH2, while the formed MgS showed no catalytic effect. The study of the evolution and catalytic mechanism of MoS2 provides theoretical guidance for the application of metal sulfides in hydrogen storage materials.

Summary: The storage of deuterium (D-2(g)) in Pd-coated Ti ultra-thin films at low pressures is fine-tuned by controlling the thicknesses of the Pd overlayer, Ti ultra-thin film domain, D-2(g) pressure, exposure duration, and film temperature. The structural properties of the Ti/Pd nanofilms are studied through various techniques to explore structure-functionality relationships. The optimized D-storage parameters and strategies are also applied to a betavoltaic battery device, showing promising performance.
