Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a pole piece softening mechanism. Background Art

[0002] During the development of the existing process, when the winding process is performed, the first section of the electrode that enters the winding process is very easy to break or fall off due to its high compaction density, thick thickness and brittle quality characteristics. Therefore, it is necessary to pre-treat the electrode before winding. After multiple process verifications, a solvent softening process was obtained, which can pre-treat the electrode for softening. The amount of solvent used is small, the softening effect is good, and the softening effect can be applied to this process after winding verification. However, the electrode needs to be quickly sent into the winding process after the softening pre-treatment to ensure its softening effect.

A electrode sheet softening mechanism needs to be added before the positive electrode sheet enters the winding process to control the softening effect of the electrode sheet to effectively avoid the breakage and falling of the electrode sheet during the winding process, thereby improving battery processing efficiency and reducing production costs.
