| titleOfInvention | A kind of silicon carbon composite material and preparation method thereof |
| abstract | A method for preparing a silicon-carbon composite material, comprising the following steps: (1) dissolving ethyl orthosilicate, cetyltrimethylammonium bromide, a catalyst and a transition metal ion in an alcohol solution, and stirring to obtain a solution A (2) Allocate alcohol-water mixed solution B; (3) Add solution A to solution B, stir to obtain emulsion C, stand and centrifuge to obtain solid matter, wash and dry, and calcinate at high temperature to obtain powder D; (4) powder D; D is reduced at high temperature, cooled and washed, and covered with carbon by vapor deposition to obtain a silicon-carbon composite material. The silicon-carbon composite material takes silicon-carbon material as the matrix, the silicon material and the carbon material in the matrix are evenly distributed, the matrix material is doped with transition metal ions, and the matrix is covered with a carbon coating layer. In the invention, the liquid silicon source and the liquid carbon source are fully mixed and then reduced and sintered to obtain a composite negative electrode material with uniform distribution of silicon and carbon; at the same time, transition metal ions are used to dope the matrix material to improve the conductivity and cycle stability of the material. |
