| titleOfInvention | A kind of graphite negative electrode composite material and preparation method thereof and lithium ion battery |
| abstract | The invention provides a graphite negative electrode composite material, a preparation method thereof, and a lithium ion battery. The graphite negative electrode composite material includes porous graphite doped with conductive carbon material and a coating layer located on its surface; the coating layer includes a porous oxide layer; based on the total mass of the graphite negative electrode composite material as 100%, the The mass percentage of the coating layer is 1-10%. The invention improves the fast charging performance of the battery by oxidizing the surface of the graphite material to form pores to grow the conductive carbon material, and depositing a porous oxide shell layer on the outer surface of the graphite material to improve the first efficiency of the lithium ion battery. |
