| titleOfInvention | Method for preparing silicon-carbon composite material based on ball milling method and application thereof |
| abstract | The invention relates to a method for preparing a silicon-carbon composite material based on a ball milling method and application thereof, belongs to the technical field of lithium ion batteries, and particularly relates to a silicon-carbon composite material prepared by the ball milling method in an air atmosphere and application thereof to a lithium ion battery cathode material, which solve the technical problem that the silicon-carbon composite material prepared by the ball milling method needs inert atmosphere protection. The solution is as follows: the nano silicon powder and the carbon material are mixed, and the high-content silicon-carbon composite is directly prepared in the air atmosphere by a ball milling method without inert atmosphere protection by adding the high-temperature molten salt phase-change heat storage material. The method reduces the filling of inert atmosphere, reduces the requirements on ball milling equipment, and ensures the content of silicon in the silicon-carbon composite material, thereby being beneficial to improving the specific capacity value of the composite material. |
