Abstract: The growing need for higher energy density in rechargeable batteries necessitates the exploration of cathode materials with enhanced specific energy for lithium-ion batteries. Due to their exceptional cost-effectiveness and specific capacity, lithium-rich manganese-based cathode materials (LRMs) obtain increasing attention in the pursuit of enhancing energy density and reducing costs. The implementation has faced obstacles in various applications due to substantial capacity and voltage degradation, insufficient safety performance, and restricted rate capability during cycling. These issues arise from the migration of transition metal, the release of oxygen, and structural transformation. In this review, we provide an integrated survey of the structure, lithium storage mechanism, challenges, and origins of LRMs, as well as recent advancements in various coating strategies. Particularly, the significance of optimizing the design of the cathode electrolyte interphase was emphasized to enhance electrode performance. Furthermore, future perspective was also addressed alongside in-situ measurements, advanced synthesis techniques, and the application of machine learning to overcome encountered challenges in LRMs.
