A clamping system for fixing in position a stack of electrode foils for the downstream manufacturing of battery cells, including a base plate, a pressure plate, at least two clamping elements and a receiving region for receiving the stack between the base plate and the pressure plate, the clamping elements clamping together the base plate and the pressure plate in a way that enables the electrode foils to be fixed in position in the receiving region, the clamping elements being located in the edge regions of the respective long sides of the plates outside of the receiving region, and/or the base plate and the pressure plate each having a plurality of, however, at least two, attachment points for connecting the clamping system to apparatuses of the downstream battery cell production in that the attachment points of a particular plate are differently embodied in the shape or size thereof.

A method for cutting a continuous battery electrode material in order to produce battery electrodes includes providing a continuous battery electrode material and providing a transport device which is designed to move the continuous battery electrode material in a movement direction from a starting point to an end point over a machining region, wherein the transport device comprises at least two transport units. Additionally, at least one cutting device is provided. The continuous battery electrode material is then machined while being moved in the movement direction by means of the at least one cutting device such that at least one machining step is carried out on the continuous battery electrode material. At least one dimension of at least one of the at least two transport units is smaller than at least one dimension of the continuous battery electrode material at least in one region.

The invention relates to a method for producing a cathode apparatus () for a battery (), especially of a motor vehicle (), whereby a cathode strip () is provided, whereby a cathode () is cut out of the cathode strip (), whereby the cathode () is placed between two strip-shaped separator foils (), and whereby, in a joint step, the two separator foils () are cut to size in an area that protrudes beyond the cathode (), thereby forming appropriate separator foil cutouts (), and these two separator foil cutouts () are also joined to each other in this area, especially fused together. Furthermore, the invention relates to a method for producing a cathode apparatus (), whereby a single strip-shaped separator foil () is folded and arranged on the cathode () in such a way that the folded edge of the separator foil () adjoins a contact face () of the cathode () and so that the cathode () is covered on both sides by a separator foil section () of the separator foil (). Furthermore, the invention relates to a method for producing an electrode assembly () having such a cathode apparatus (), to a battery () having such an electrode assembly (), as well as to a motor vehicle () having such a battery ().
