| titleOfInvention | Preparation method of silicon-carbon negative electrode material, silicon-carbon negative electrode material and lithium ion battery |
| abstract | The invention belongs to the technical field of lithium ion batteries, and relates to a preparation method of a silicon-carbon negative electrode material, the silicon-carbon negative electrode material and a lithium ion battery. The preparation method of the silicon-carbon negative electrode material provided by the invention comprises the following steps: (a) heating SiO to make it generate disproportionation reaction to generate c-SiO; (b) placing the C-SiO in a chemical vapor deposition furnace, heating the furnace in a protective atmosphere, introducing a carbon source after the temperature is raised to a reaction temperature, and carrying out vapor deposition reaction to obtain C-SiO/C, wherein the carbon source is a liquid or solid compound; (c) and corroding the C-SiO/C by using corrosive liquid to obtain the silicon-carbon negative electrode material C-SiO/Si/C. The invention has simple process and easy operation, and the prepared silicon-carbon cathode material has the high lithium storage property of silicon materials and the high cycle stability of carbon materials, and has high specific capacity, good conductivity and good cycle performance. |
