| titleOfInvention |
Modified graphite negative electrode material, preparation method thereof and battery containing modified graphite negative electrode |
| abstract |
The application discloses a modified graphite cathode material, which comprises a graphite main body material and a carbon fluoride material, wherein the chemical formula of the carbon fluoride material is CF x . The graphite cathode with the carbon fluoride material protective layer has the functions of stabilizing and reinforcing a solid electrolyte interface film and guiding lithium ions to be uniformly embedded and separated on the graphite cathode, so that the battery assembled by the modified graphite cathode material has obviously improved performance. The invention also discloses a preparation method of the modified graphite cathode material and a preparation method of a lithium ion battery. |
