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.

A cell feeding method includes: controlling a first conveyor line to convey inflowing cells to a first material fetching position; controlling a second conveyor line to convey inflowing cells to a second material fetching position; controlling a third conveyor line to convey inflowing cells to a side taping station, and conveying the cells subjected to side taping treatment to a third material fetching position; controlling a first feeding and grabbing mechanism to grab a first number of cells from a first material fetching position to a first feeding area in the feeder position; and controlling a second feeding and grabbing mechanism to grab a first number of cells from a target material fetching position to a second feeding area in the feeder position.
