METHOD FOR PRODUCING A CATHODE APPARATUS, METHOD FOR PRODUCING AN ELECTRODE ASSEMBLY, AND BATTERY

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 ().
