LiMn2O4 (LMO) has established its own niche in the highly competitive market of cathode materials. However, issues such as oxygen evolution, manganese dissolution, and electrolyte decomposition have hampered its further development. To address these challenges, a simple and effective strategy has been proposed, which involves incorporating WO2.72 as an oxygen vacancy inducer into LMO to enhance its structural stability. It is demonstrated that WO2.72 can induce the formation of oxygen vacancies on the material surface, which aids in the adsorption and storage of active oxygen. The vacancies also reduce the energy barrier for the migration of lithium ions, thus improving the electrochemical performance of the battery. Additionally, the formation of a Li2WO4 coating helps to eliminate residual lithium and improve the interface between the electrode and electrolyte. Accordingly, the WO2.72-modified LMO exhibits a more stable bulk structure and a better electrode-electrolyte contact interface, resulting in superior electrochemical performance. The optimized W4000 sample demonstrates outstanding cycle performance, with a capacity retention of 90.4% after 300 cycles at 10 C, which is significantly higher than that of bare LMO (68.9%).
