Abstract

The invention discloses a solid-state silicon-carbon-lithium-tantalum battery negative electrode material carbon coating device, and particularly relates to the technical field of battery processing equipment. The solid-state silicon-carbon-lithium-tantalum battery negative electrode material carbon coating device comprises a coating tank, support legs, a discharge port and a feeding port, the support legs are fixedly connected to four corners of the bottom end of the coating tank, and the discharge port is formed in the bottom end of the coating tank. By arranging the opposite stirring mechanism, the opposite stirring mechanism comprises the driving box, the driving box is fixed to the front end of the coating tank, the driving shaft is movably connected to the interior of the driving box, the servo motor is arranged on one side of the driving box, and during use, the servo motor is started and drives the driving shaft to rotate; the driving shaft drives the first gear and the secondgear to rotate oppositely through the driving blades arranged outside the driving shaft, so that the first stirring shaft and the second stirring shaft are driven to stir the interior of the driving shaft, the carbon coating efficiency can be improved, a centrifugal force generated during stirring can be prevented, and the carbon coating efficiency and the carbon coating effect are greatly improved.

Description

technical field [0001] The invention relates to the technical field of battery processing equipment, in particular to a carbon coating device for a solid silicon carbon lithium tantalum battery negative electrode material. Background technique [0002] Lithium battery anode materials need to be coated with carbon to overcome the defects of a single material, so that it has excellent electrochemical performance. Solid silicon carbon lithium tantalum batteries are a type of lithium batteries, so the battery anode materials need to use carbon in the production process.
