| Abstract: | Research progress in composite materials Li2MnO3-LiMO2(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 post-treatment methods of these materials and their effects for improvement of coulombic efficiency of initial charge/discharge and rate capability were highlighted.After post-treatment with electrochemical activation,dilute acid,surface coating etc,the irreversible capacity of the first charge/discharge cycle was reduced,rate performance and cycle stability were improved. |
