Description

Technical Field

[0001] The utility model relates to the technical field of graphite negative electrode material coating, and more specifically, to a graphite negative electrode material coating and modification device. Background Art

[0002] The modification process of graphite negative electrode materials requires one or more coatings to form a complete, uniform, and firm coating layer on the graphite surface. Single-coated graphite refers to graphite whose surface has been coated once with a coating agent. The coating agent used in the single coating process can be a conventional surface coating agent. Existing graphite negative electrode material coating and modification devices, during long-term use, uneven material feeding will lead to large differences in the ratio of graphite negative electrode material and coating material in different parts. During the material addition process, it is easy to cause material accumulation, resulting in material blocking the feed port, making the device unable to operate normally. The quality of each batch of products fluctuates greatly, which may lead to unstable endurance of the equipment, shortened lifespan, and even safety hazards. Therefore, improvement and optimization are needed. Utility Model Content
