摘要 综述了锂离子电池复合正极材料Li2MnO3-LiMO2(M=Co、Ni和Mn)的研究进展;重点介绍了首次充放电过程中组成及结构的变化以及为改善首次充放电效率和倍率性能所进行的后处理。通过电化学活化、酸处理、表面包覆等方法处理后,该类材料的首次充放电不可逆容量可降低,倍率性能及循环稳定性可得到很大提高。 Research progress in composite materials Li2 Mn03- LiM 02 （ M = Co, Ni, Mn）as promising cathode candidates for Li-ion battery was summarized.Particularly, the changes of composition and structure during initial charge/discharge process and posttreatment methods of these materials and their effects for improvement of coulombie efficiency of initial charge/discharge and rate capability were highlighted. After post-treatment with electrochemical activation, dilute acid, surface coating ere, the irreversible capacity of the first charge/discharge cycle was reduced, rate performance and cycle stability were improved.
