The invention discloses a preparation method of an aluminum oxide coated lithium cobaltate positive electrode material, and the lithium cobaltate surface is evenly coated with an alumina thin film by vapor phase deposition method. The preparation process is as follows: mixing evenly an aluminum-containing compound and lithium cobaltate in a converter, heating the aluminum-containing compound for vaporization, then introducing water vapor to allows the aluminum-containing compound to be hydrolyzed into aluminum hydroxide for deposition onto the lithium cobaltate surface, and heating to obtain the aluminum oxide coated lithium cobaltate positive electrode material. The method has the advantages that the preparation process is simple and suitable for large-scale production, the synthesized aluminum oxide coated lithium cobaltate positive electrode material is coated evenly with the alumina and excellent in cycle stability.
