What should you pay attention to during the rolling process of lithium ion battery anode materials?

As a lithium-ion battery company, the raw material is ultimately presented as a product in front of consumers. When a negative electrode material is obtained, how can the material be used well and the performance of the material itself can be exerted? The responsibility is.

Rolling process

When the negative electrode piece that has passed the homogenization and coating process is completed, the next process is crushing. Why should it be crushed? Because the surface state of the coated pole piece is relatively loose, the thickness is relatively thick, and the bonding force is not necessarily ideal. By rolling, the contact between the particle and the particle is tight, and the thickness is reduced, thereby achieving the design requirement.

The parameters to be tested during the rolling process are similar to the coating, mainly the thickness control and the consistency of the thickness. In order to achieve high energy density, the coating density of the negative electrode is now higher and higher, thus deriving two mills. Pressing, heating and rolling, etc., are all designed to make the negative electrode better pressed to the required thickness, and it needs to be applied according to the actual situation.
