| titleOfInvention | Method for preparing silicon-carbon composite negative electrode material by low-temperature plasma |
| abstract | The invention discloses a method for preparing a silicon-carbon composite negative electrode material by using low-temperature plasma, which comprises the following steps of: adding nano silicon, a silane coupling agent, an additive and a catalyst into an organic solvent, mixing and stirring uniformly, and carrying out low-temperature plasma technology treatment, ultrasonic dispersion, chemical vapor deposition and surface modification thereof to obtain the silicon-carbon composite negative electrode material. The invention has the beneficial effects that: according to the invention, the silane coupling agent and the catalyst are processed by a low-temperature plasma technology to generate charged particles and active ingredients to act on the nano-silicon, and then the charged particles and the active ingredients are carbonized and reduced to obtain the nano-silicon/silicon monoxide composite material, wherein the composite material has the characteristics of high specific capacity, strong structural stability, high consistency and the like, so that the cycle performance of the material is improved. |
