Research Process on Layer Cathode Material for Li-ion Batteries

文章主要综述当前锂离子电池层状正极材料—LiCoO2、LiNiO2、LiMnO2的研究进展。阐述了三种层状盐结构正极材料的优缺点,对LiCoO2和LiNiO2正极材料的改性方法:掺杂和包覆处理。通过改性,层状正极材料的结构和性能均有较大改善,为锂离子电池更为广泛的工业应用指明道路。对锂离子电池正极材料未来的应用前景做了一些展望。

The paper mainly introduced the research process on layer cathode materials- LiCoO2, LiNiO2, Li MnO2 at present. The advantages and disadvantages of the three layer cathode materials were displayed, and also ways of the modification of LiCoO2 and LiNiO2： doping and coating. The structure and the properties of the layer cathode materials are prompted severely through modification which pointed out a way for the more widely apply of Li-ion batteries. What was more, I showed a prospect of apply of the cathode materials on Li-ion batteries.
