The invention provides a lithium cobalt oxide precursor with a coating structure, its preparation method and application, the preparation method comprising: mixing and stirring a cobalt source doped with a metal element and a metal salt solution, adding lye Stirring is continued to obtain a precursor mixture, and the precursor mixture is sintered to obtain a lithium cobalt oxide precursor with a coating structure. This application adopts the liquid phase synthesis method to coat the metal hydroxide on the surface of the lithium cobalt oxide precursor, so that the coating is more uniform, and the coating layer can exist stably, and a stable solid solution coating can be formed in the subsequent sintering process The interface makes the material structure more stable and the electrochemical performance is more excellent. |
