| titleOfInvention | Regenerated graphite material and preparation method thereof |
| abstract | The invention belongs to the technical field of recovery and recycling of battery materials, and particularly relates to a regenerated graphite material and a preparation method thereof. The preparation method of the regenerated graphite material comprises the steps of carrying out acid leaching, water washing and heating treatment on the lithium ion battery negative electrode feed back to obtain powder I, mixing the powder I with a carbon source, coating the carbon source on the surface of the powder I to obtain powder II, and coating the organic carbon source on the surface of the powder II by a chemical vapor deposition method to obtain the regenerated graphite material. The preparation method of the regenerated graphite material removes most of substances influencing the primary efficiency and the electric capacity in the cathode return material through acid leaching, water washing and heating treatment, and then secondary carbon coating is carried out, and the secondary carbon coating is carried out through a chemical vapor deposition method, so that the obtained regenerated graphite material has a uniform, compact and complete interface, high capacity and higher primary efficiency. |
