Abstract

Abstract:

Lithium rich layered oxide cathode materials (xLi₂MnO₃·(1-x)LiMO₂(M=Ni_yMn_zCo_1-y-z….) are one of the candidate cathode materials for the new generation of lithium ion batteries because of the high theoretical capacity and low cost. In this paper, the structure of the cathode materials and the structure activation and evolution within initial charge-discharge and the cycling process were outlined, the effect of structure evolution on electrochemical evolution of the Li-rich cathode materials were further investigated. And, the current works of ion doping and surface modification on the cathode materials to enhance electrochemical properties were summarized and the development trend of different lithium rich layered oxide cathode materials was described.
