Description

Technical Field

[0001] The utility model relates to the technical field of silicon-carbon negative electrode material production lines, and more specifically to a uniform heating auxiliary mechanism of a silicon-carbon negative electrode material production line based on a CVD method. Background Art

[0002] Silicon-carbon composite anode material is a new type of lithium-ion battery anode material developed in recent years. It consists of silicon-based active materials and carbon-based conductive materials. Silicon-based active materials can provide high capacity and good energy density, while carbon-based conductive materials can provide good conductivity and thermal stability. Therefore, carbon composite anode materials have good comprehensive properties and can effectively improve the energy density and cycle life of batteries.

[0003] When using the CVD method to produce and process silicon-carbon negative electrode materials, the workpiece needs to be heated. However, during the heating process, the heat generated by the heat source cannot be effectively dispersed, which can easily cause differences in the heating of local positions of the workpiece, which is not conducive to uniform heating. Therefore, we proposed a uniform heating auxiliary mechanism for the silicon-carbon negative electrode material production line based on the CVD method to solve the above-mentioned problems.
