Battery cell lamination system and method

The embodiment of the invention discloses a battery cell lamination system comprising a lamination table and a diaphragm assembly; the diaphragm assembly is arranged above the lamination table; the diaphragm assembly is used for introducing a diaphragm into the lamination table, the lamination table is provided with a plurality of pole piece placing areas, and the lamination table is divided into two rows and multiple columns of pole piece placing areas according to the positions of slitting lines; and the pole pieces are placed on the lamination table according to the pole piece placing areas and are distributed in two rows and multiple columns. According to the battery cell lamination system provided by the invention, the lamination table is divided into a plurality of pole piece placing areas which are distributed in two rows and multiple columns according to the positions of the slitting lines, so that the pole pieces are distributed in two rows and multiple columns on the lamination table, a lamination process of simultaneously stacking the pole pieces on the same lamination table is realized, and the lamination efficiency is improved; and through the film covering process that the diaphragm assembly covers multiple pole pieces at a time, the film covering efficiency is improved, the production period is effectively shortened, and the time cost is saved. The invention also provides a battery cell lamination method.
