Title:
BATTERY CELL MANUFACTURING DEVICE AND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/169219
Kind Code:
A1
Abstract:
The present application relates to a battery cell manufacturing device, comprising a first feeding apparatus, a second feeding apparatus, a separator feeding apparatus and a winding apparatus. A first wide pole piece is divided into two parts after being cut by a first cutting mechanism, to obtain two first pole pieces, a side edge of each first electrode plate being provided with a first tab region. A second wide pole piece may also be divided into two parts after being cut by a second cutting mechanism, to obtain two second pole pieces, a side edge of each second electrode plate being provided with a second tab region. The two first pole pieces and the two second pole pieces are aligned with each other in an one-to-one correspondence, and enter the winding device together with a separator provided by the separator feeding device. In this way, a needle winding mechanism may simultaneously form two battery cells in one winding, and the tabs of the battery cells are located on two sides. Therefore, the described battery cell manufacturing apparatus is able to further improve the production efficiency of battery cells.
