Abstract (en)
[origin: WO2018059971A1] The invention relates to a method for producing a film stack for a battery cell, having the following steps: providing a separator film (4) with at least one first layer (6), which has a polyolefin, and at least one ceramic layer (8), removing the ceramic layer (8) at defined locations (10) of the separator film (4) by means of a laser, arranging a first electrode film on the separator film (4), connecting the separator film (4) to another separator film at the locations where the ceramic layer (8) has been removed or to itself after a folding process in order to form a pocket in which the first electrode film is arranged, and arranging pockets produced in this manner and second electrode films in order to form film stacks.
