Abstract
A method for producing a cell stack for battery cells comprises at least the following steps: feeding in at least a first material strip consisting of a first material; making a first cut into at least the first material strip while forming at least one transport section having tensile strength; combining the first material strip with at least a second material strip consisting of a second material, so as to form a partial stack; making a second cut of the partial stack, whereby the transport section is cut open; and arranging at least two partial stacks so as to form a cell stack.
