Description

technical field [0001] The invention relates to the field of CVD process equipment, in particular to a CVD process-based process equipment for producing silicon-oxygen negative electrode materials. Background technique [0002] When the silicon-oxygen negative electrode material battery material is fired, it is necessary to crack the hydrocarbon gas into carbon and hydrogen at a high temperature in a trace oxygen environment. The carbon deposition is coated on the surface of the silicon-oxygen negative electrode material raw material, and then fired at high After obtaining the product, the CVD process needs to meet the following technical characteristics: [0003] 1), high temperature environment: usually 900 ℃ ~ 1050 ℃; [0004] There are two types of cylinder material, metal material and non-metal material. Due to the manufacturing process, the non-metal material cannot be too large in size, so the output is limited, and it can only be used in small laboratory equipment. ...
