Method for producing an electrode stack for a battery cell, battery cell

Abstract

The invention relates to a method for producing an electrode stack for a battery cell, comprising the following steps: providing a strip-shaped anode element (45) comprising an anodic current discharger (31) to which an anodic active material (41) is applied; providing a strip-shaped cathode element (46) comprising a cathodic current discharger (32) to which a cathodic active material (42) is applied; providing at least one strip-shaped separator element (16); introducing grooves (70) into the cathodic active material (42) around segmentation lines (S); generating a strip-shaped composite element (50) by applying the cathode element (46) onto the anode element (45), with the interposition of the at least one separator element (16); cutting the composite element (50) into plate-shaped composite segments at the segmentation lines (S); and stacking the composite segments. The invention also relates to a battery cell comprising at least one electrode stack which is produced according to the method according to the invention.
