Abstract

The present application relates to a pole piece folding control method and apparatus, a pole piece folding apparatus, and a battery production system. During the folding process of a pole piece group, a conveying component is controlled to operate, and the pole piece group is driven to move towards a stacking platform. When a lamination area on the stacking platform starts to fold or has been folded, at least one of the conveying component and the stacking plaform is controlled to move such that the distance between a conveying end of the conveying component and at least part of an operating surface of the stacking platform is pulled open. In this way, a clearance space can be provided for folding of the lamination area, thereby facilitating stress relief of the lamination area during folding, reducing a pulling force of the lamination area in a folded state on a non-folded lamination area, and reducing a degree of bending and warping of the lamination area at a folding position. Thus, the probability of abnormal gaps being generated at the folding position of a laminated structure is reduced, thereby effectively reducing the probability of lithium deposition at the folding position of the electrode, and improving the quality of the laminated battery.
