[0002] The pole piece is a key part of the chemical reaction in the battery. It is responsible for storing and releasing energy during the battery's charge and discharge process. The quality of the pole piece directly affects the battery's performance, including its energy density, cycle life and safety. A pole piece roller press is needed in the pole piece processing process. The pole piece roller press is a device used to compact the pole piece in lithium battery manufacturing. It compacts the active material in the battery pole piece through physical pressure to improve the battery's energy density and life. The pole piece roller press plays an important role in lithium battery production, which not only affects the quality of the product, but also is related to production efficiency and cost control.

[0003] The existing roller press device is not convenient for compacting the pole piece by using independent bending cylinders and convex rollers, and is not convenient for increasing the roller bending cylinder force, increasing the reverse deflection deformation of the roller to compensate for the deflection value. At the same time, it does not adopt the roller type design of the convex roller, and cannot change the lateral distribution of the roller surface diameter, compensate for the roller surface deflection deformation difference, and correct the roller deflection deformation, which reduces the practicality of the device; therefore, we propose a pole piece roller press that can correct the roller deflection deformation to solve this problem.
