Abstract: A peeling device for manufacturing of an electrode stack includes an upper wedge and a lower wedge between which the electrode stack is fed after a calendering process. A respective lifting roller may be located at the output ends of each of the wedges, which through coordinated action peels the aluminum layers away from the corresponding layer of the electrode stack. The peeling force, exerted by rollers capturing upper and lower aluminum foil sheets of the stack, may be controlled and relatively uniform, thereby enhancing the ability to peel the foil from the stack while not damaging the relatively delicate remaining layers. The aluminum foil is directed away from the stack along an outer planar surface of the respective wedge where the foil can then be wound around the respective rollers.
