Description

Technical Field

[0001] The utility model relates to the field of carbon coating, in particular to a preparation device for carbon coated silica sand. Background Art

[0002] Silicon-carbon negative electrode materials are generally produced by carbon coating, which can restrain and buffer the volume expansion of silicon, prevent the agglomeration of nano-active particles, prevent the electrolyte from penetrating to the center and maintain a stable interface. Therefore, new energy vehicle manufacturers have a great demand for carbon coating devices. The lithium battery carbon coating devices currently on the market introduce nitrogen to replace the air in the reaction chamber during silicon-carbon coating. However, the speed at which nitrogen replaces the air in the reaction chamber is slow, and the air in the reactor cannot be discharged in time, so the coating effect is incomplete. At the same time, the volatilized gas of the reaction materials added inside is toxic. The existing recovery devices are costly and have poor safety, which is not conducive to safe production. Therefore, a preparation device for carbon-coated silica sand is proposed. Utility Model Content
