Abstract: The cathode materials for lithium ion batteries xLi₂MnO_3^-(1-x)LiNi_0.7Co_0.3O₂ were prepared via low temperature combustion process. The structure, morphology and electrochemical performance of the synthesized materials were studied systematically. The optimal preparing conditions and the optimal ratio of Li₂MnO₃ for the cathode materials were studied by single factor experiment. The experimental results show that the synthesized products have α-NaFeO₂ layered structure, sphere-like morphology and excellent electrochemical performance; the optimal conditions to prepare these materials are to reheat the combustion products at 850℃ for 20 h, the optimal ratio of Li₂MnO₃ is x=0.7. The cathode material 0.7Li₂MnO₃-0.3LiNi_0.7Co_0.3O₂ synthesized under such conditions has the highest discharge capacity of 263.1 mAh·g^-1, excellent cycle and rate performance.
