[0002] Silicon-carbon composite materials refer to new materials formed by combining silicon materials with carbon materials. The structure of silicon-carbon composite materials consists of silicon particles and carbon matrix. Silicon materials have high specific capacity and low potential, while carbon materials have excellent conductivity and cycle stability. Therefore, silicon-carbon composite materials have high specific capacity, low potential and good cycle stability, and are an ideal negative electrode material.

[0003] In the prior art, during the production and processing of silicon-carbon composite materials, it is necessary to stir and mix silicon materials and carbon materials. The existing mixing structures are mostly cylinders with built-in stirring rods. Since the stirring rods are mostly located in the middle of the cylinder, they do not contact the inner surface of the cylinder during the rotation and stirring process, resulting in insufficient stirring of the silicon-carbon material mixture located on the inner wall of the cylinder, which in turn affects the production and processing of the silicon-carbon composite materials.

[0004] Therefore, it is necessary to invent a silicon-carbon negative electrode composite material stirring device. Utility Model Content
