Surface Modifications of Magnesium-Based Materials for Hydrogen Storage and Nickel–Metal Hydride Batteries: A Review

Whether it is fossil energy or renewable energy, the storage, efficient use, and multi-application of largely depend on research preparation high-performance materials. The development storage materials with a high capacity, long cycle life, safety, cleanability will improve properties systems promote their wide application. In recent years, Mg-based materials, from comprehensive consideration performance, raw material reserves, prices, have demonstrated potential industrial applications as large-scale hydrogen Nevertheless, also obvious disadvantages: material, absorption/desorption rate insufficient, well temperatures; electrode Ni-MH batteries, reactions Mg alkaline electrolyte corrosion are main problems for applications. This article reviews different surface treatment methods mechanisms modifications battery applications, performance after modifications. Multiple experimental studies shown that layer state has strong impact performance. Surface modification can greatly magnesium-based Specifically, lower temperature faster when used resistance, initial discharge cycling stability in solutions negative batteries. By offering an overview two fields, this researchers’ understanding mechanism contribute to improving more targeted manner. While properties, material’s process considered comprehensively development, production, application
