Background
Rolling is the most commonly used compaction process for battery pole pieces, and can change the pole piece hole structure and the distribution state of the conductive agent, thereby influencing the electrochemical performance of the battery. However, since the film coating area of the battery pole piece is thicker than the empty foil area (also called tab), in the rolling process, the film coating area is rolled to be stretched, but the empty foil area is not rolled to be stretched due to being too thin, so that the film coating area and the empty foil area are not stretched uniformly, and wrinkles are generated at the empty foil area. This fold can influence utmost point ear welding strength, leads to welding failure or increase battery resistance, and the battery charge-discharge in-process generates heat soon, and cycle life decay accelerates, and it pierces through to possibly cause the diaphragm, causes the short circuit, produces the potential safety hazard.
In order to eliminate folds of the empty foil area, the prior art means is that when the battery pole piece is rolled, an adhesive tape is manually stuck on a swinging roller of a stretching mechanism in a region corresponding to the empty foil area of the pole piece, so that the empty foil area can be rolled to eliminate the folds when the empty foil area is rolled. However, the manual tape sticking has high technical requirements, and the tape sticking process needs to be slowly performed to prevent the tape from sticking off or generating wrinkles; when the adhesive tape is cut, the consistency of the upper and lower layer cuts is ensured. Meanwhile, because the thicknesses of different pole pieces are different, the thickness of the adhesive tape on the swinging roller is required to be adjusted when the pole pieces are replaced, and extra workload is increased.
