Lithium ion battery cathode material of which nano particles embedded into carbon nanosheet and preparation method of lithium ion battery cathode material

The invention discloses a lithium ion battery cathode material of which nano particles are embedded into a carbon nanosheet and a preparation method of the lithium ion battery cathode material, which belong to the technical field of electrochemistry. According to the method, water-soluble organic matter (glucose, saccharose, fructose, citric acid, sodium citrate and the like) is used as a carbon source, commercial submicron particles (such as metallic tin, stibium, germanium, nonmetallic silicon and the like) are used as a particle source, sodium chloride is used as a template, the carbon source, the submicron particles and the sodium chloride are added into a ball milling tank for ball milling according to a proper proportion, and a mixture is dried and calcined. A simple ball milling method and a pyrolysis method are used for preparing the lithium ion battery cathode material of which the nano particles are uniformly embedded into the carbon nanosheet. According to the lithium ion battery cathode material of which the nano particles are uniformly embedded into the carbon nanosheet, the specific surface area is large, the surface is of a porous structure, the preparation method is simple, and the lithium ion battery cathode material has good circulation and rate performance.
