METHOD OF PRODUCING AN ELECTRODE-SEPARATOR WINDING, ELECTRODE-SEPARATOR WINDING AND BUTTON CELL WITH SUCH A WINDING

摘要

A method of producing an electrode-separator winding includes feeding a first current collector, feeding a second current collector, feeding two separators in strip form to a winding device, and winding the first and second current collectors and the separators to form a winding with a sequence, wherein a contact strip is welded on at least one of the contact sections of the current collectors, or at least one of the contact sections is folded over to form a contact strip, and at least one of the separators is reinforced in at least one risk region in which the at least one separator within the completed electrode-separator winding lies against the at least one contact section in which the contact strip is welded on or against the at least one contact section folded over to form a contact strip.
