description The invention discloses a high-performance alkaline zinc battery cathode material and a preparation method thereof. The high-performance alkaline zinc battery cathode material can be directly used as a flexible alkaline zinc battery cathode, conversion from cobalt diselenide to selenium-doped cobalt oxide is achieved by means of an initial electrochemical cycle process, depending on the maintaining effect of selenium doping on the content of high-valence cobalt in the cobalt oxide, high area specific capacity and long cycle stability superior to those of conventional cobalt oxide are obtained, the service life reaches 10000 times or above, and the zinc-storage cathode material is far superior to most of current zinc-storage cathode materials. The preparation method provided by the invention is simple and easy to implement, green and environment-friendly, mild and controllable in reaction, low in requirements on equipment conditions and relatively low in production cost, and the obtained high-performance alkal
