Abstract

The cathode materials Li_1+xMn₂O₄ were prepared with citric acid complexing and solution impregnating methods. Structure characterization and specific surface area test were performed by means of XRD, BET methods, the influences of calcination temperature, Li/Mn molar ratio and raw materials on the structure and electrochemical capacity of samples have beem examined. The results showed that the Li/Mn molar ratio and calcimation temperature were the key factors affecting the electrochemical capacity of cathode materias. The optimum conditions for synthesis of Li_1+xMn₂O₄ cathode material were 0≤x≤0.05 and calcined at 750°C. The initial capacity of the sample reached 120 mAh/g and capacity retention after 50 cycles was 115 mAh/g.
