摘要
层状锂锰氧化物作为锂离子电池的正极材料,具有无毒、低成本、能量密度高等优点。综述了近年来锂离子电池层状正极材料的研究进展,主要讨论了层状锂锰氧化物掺杂改性对其结构和电化学性能的影响,以及多元复合材料LiMnxCoyNi1-x-yO2的结构特性、制备方法、各金属元素含量的变化对其电性能的影响。
Layered lithium manganese oxide used as positive electrode materials of lithium ion batteries has many merits such as nontoxicity,low cost,high energy density and so on. In the paper, the recent research progresses in layered structural positive electrode materials is reviewed. The effects of doped and modified layered lithium maganese oxide and structural character, synthetic method,metallic content changes of LiMnxCoyNi1-x-yO2 on its structure and electrochemical properties are all discussed.
