Recently, lithium-ion batteries (LIBs) have gained extensive applications in electric vehicles and energy storage systems due to their high density long service life. In LIBs, the overall cost highly depend on cathode material. Therefore, low-cost Mn-based spinel LiMn2O4 (LMO) has emerged as an outstanding candidate attracted attention of many scientific researchers. However, structural instability during cycling, particularly capacity deterioration at temperatures, severely hinders its commercial applications. Various studies reveal that Jahn-Teller(J-T) effect Mn disproportionation constitute primary causes irreversible phase transition dissolution induced by decline. This review first discusses interrelationships among spinel, layered, rock salt structures underlying principles LMO charging discharging process. Subsequently, we systematically decay mechanism analyze recent advancements performance enhancement strategies, with particular emphasis how partially disordered architectures exceeds theoretical limitations while achieving ultrahigh rate capability. Furthermore, rapid synthesis through advanced manufacturing processes is introduced. summarizes progress challenges pioneering research provides new ideas for practical application LMO.
