Recent Advances in Rechargeable Magnesium Battery Technology: A Review of the Field's Current Status and Prospects

The demand for new energy storage systems to be employed in large‐scale electrical energy storage systems (EESs) has grown recently, particularly for green energy storage and grid‐supporting applications. Rechargeable Mg batteries are promising candidates for such applications because of their good safety characteristics and raw materials’ abundance. Recent progress in the field is noticeable, but further efforts are required to support the successful implementation of rechargeable Mg batteries. We address progress in the development of rechargeable Mg batteries and problems to be resolved in future research, briefly summarize the most recent advances in the development of rechargeable Mg batteries, from a materials perspective, and cover progress on each of the major components of Mg batteries: the electrolyte, the cathode material, and the anode material. We provide a practical guideline for further development of self‐sustainable rechargeable Mg batteries as a future power source.
