Description

Mixing mainly uniformly mixes electrode materials (such as positive materials, negative materials), conductive agents, and adhesive agents together to ensure that these powders are evenly distributed at the microscopic level. This process is a necessary preparation process before beating. Only by ensuring the uniform mixing of the powder can the consistency and performance of the subsequent lithium battery material be ensured. However, the existing mixing device for battery material production is not convenient for fully mixing the battery raw materials during the mixing process, and after long-term use, a large amount of battery raw material residues will adhere to the stirring rod, which is not convenient for cleaning the stirring rod, and is easy to cause the efficiency of subsequent mixing.

However, the mixing device is not convenient for fully mixing the battery raw materials, and can only be mixed once, which reduces the mixing efficiency, and after long-term use, a large amount of battery raw material residues will adhere to the stirring rod, which is not convenient for cleaning the stirring rod, and is easy to cause the efficiency of subsequent mixing.
