    High nickel materials have good electrochemical performance, but there is a problem of poor surface stability. In this study, tetrabutyl titanate was hydrolyzed on the surface of NCM811 material to generate TiO2. SEM and TEM analysis results indicate that the TiO2 layer can be uniformly coated on the surface of high nickel NCM811 using the proposed method. By utilizing the combined effect of surface coating and bulk doping, the capacity retention rate of the material increased from 81.40% to 92.39% after 200 cycles under 1C discharge condition, and the electrochemical performance of NCM811 material was improved.
