Ni-rich LiNi0.8Co0.1Mn0.1O2(NCM811) cathode particles were coated with anatase TiO2layer to improve its cycle stability. The TiO2coating was synthesized by the hydrolyzation method and subsequent annealing treatment ranging from 500 ℃ to 600 ℃. The well-ordered layered α-NaFeO2-type structure survives in the TiO2coating process. The nanothick anatase TiO2layer coveres on the surface of NCM811. The annealing temperature of coating was controlled to improve the electrochemical performances. The TiO2-coated NCM811 cathode annealed at 600 ℃ demonstrates the optimal capacity retention of 104.9% after 100 cycles at the current rate of 0.1 C, in contrast to 64.1% of pristine NCM811 and 96.7% of the coated sample annealed at 500 ℃.
