Abstract:

Lithium-rich ternary layered cathode material(xLi2MnO3·(1-x)LiMO2(0<x<1, M=Mn,Ni,Co)) has much higher discharge capacity than other cathode materials. Therefore, it is regarded as one of the best choice for the next generation of lithium-ion battery cathode materials. However, its commercial production and application have been limited by its poor cycle performance and low coulomb efficiency. Herein the latest research progress of lithium-rich ternary layered cathode materials is reviewed, mainly including the progresses in the aspects of material composition, preparation technology, structure tuning, doping and coating modification of the materials. Furthermore, developing trends of the materials is also prospected in this paper.

Key words: lithium ion batteries, cycle performance, lithium-rich ternary layered cathode materials
