Summary: Rechargeable magnesium batteries (RMBs) are promising for their potential in high energy density, low cost, and high safety. However, technological breakthroughs are required for commercialization. Cathode materials are crucial for the commercialization of RMBs as they directly affect energy and power densities. The main challenge lies in the poor diffusion of Mg2+ ions in electrode materials due to strong interaction with host materials. Various attempts have been made to overcome this issue, including synthesis of new materials, morphological modifications, doping, substitution, and addition of second components. This review provides additional information on recent developments in cathode materials for RMBs in the past 3-4 years, as well as perspectives and challenges for future development.
