Abstract: In recent years, the Li-rich materials xLi₂MnO₃·(1-x) LiMO₂(M=Ni, Co, Mn) for lithium ion battery have gained much attention for its low cost and high discharge specific capacity. However, Li-rich materials failed to be mass produced for their advantages of huge irreversible capacity loss, inferior cyclic performance, poor rate capability and voltage decay. Li-excess layered cathode materials LiLi_0.2Mn_0.54Co_0.13Ni_0.13O₂ were synthesized by a fast co-precipitation method. Its electrochemical performance, especially cyclic performance, was greatly improved by ZrO₂ coating.
