Description

Technical Field

[0001] The utility model relates to the technical field of vapor deposition, in particular to a cold wall type microwave device for producing silicon carbon materials. Background Art

[0002] Silicon negative electrode materials have become the most likely new generation of negative electrode materials to replace traditional graphite negative electrode materials due to their advantages such as higher theoretical capacity, lower discharge platform and abundant reserves. The performance of electrode materials depends not only on their chemical composition, but also on their particle microstructure. The choice of synthesis method is the key to manufacturing commercial electrode materials. The synthesis or forming methods of Si / C composite materials are generally CVD rotary kiln, fixed bed, moving bed, fluidized bed, and ebullient bed CVD rotary kiln.

[0003] Patent publication number CN 220812614 U discloses a cold-wall microwave device for producing silicon-carbon materials.
