description The invention relates to the technical field of a lithium ion negative electrode material, and discloses a dried-persimmon-type core-shell-structured C/ZnO lithium ion battery negative electrode material and a preparation method thereof. Absolute ethanol, zinc acetate dehydrate, ethanolamine and glucose are taken as raw materials, and the time and temperature of a hydrothermal reaction is strictlycontrolled to prepare a dried-persimmon-type core-shell-structured C/ZnO material. Compared with a ZnO negative electrode material in the prior art, the dried-persimmon-type core-shell-structured C/ZnO with a special shape is greatly improved in conductivity and stability and obviously improved in electrochemical performance. According to the lithium ion battery negative electrode material, stress variation due to size variation in a charge-discharge process is reduced, and the dried-persimmon-type shape increases the specific surface area, so that the cycle performance of a lithium ion battery is efficiently improve
