PG - 159 LID - 10.3389/fchem.2018.00159 [doi] LID - 159 AB - Lithium-rich manganese-based cathode materials has been attracted enormous interests as one of the most promising candidates of cathode materials for next-generation lithium ion batteries because of its high theoretic capacity and low cost. In this study, 0.5Li(2)MnO(3).0.5LiNi(0.5)Co(0.2)Mn(0.3)O(2) materials are synthesized through a solid-state reaction by using different lithium sources, and the synthesis process and the reaction mechanism are investigated in detail. The morphology, structure, and electrochemical performances of the material synthesized by using LiOH.H(2)O, Li(2)CO(3), and CH(3)COOLi.2H(2)O have been analyzed by using Thermo gravimetric analysis (TGA), X-ray diffraction (XRD), Scanning electron microscope (SEM), Transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), and electrochemical measurements. The 0.5Li(2)MnO(3).0.5LiNi(0.5)Co(0.2)Mn(0.3)O(2) material prepared by using LiOH.H(2)O displays uniform morphology with nano particle and stable layer structure so that it suppresses the first cycle irreversible reaction and structure transfer, and it delivers the best electrochemical performance. The results indicate that LiOH.H(2)O is the best choice for the synthesis of the 0.5Li(2)MnO(3).0.5LiNi(0.5)Co(0.2)Mn(0.3)O(2) material.
