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 () comprising an anodic current discharger () to which an anodic active material () is applied; providing a strip-shaped cathode element () comprising a cathodic current discharger () to which a cathodic active material () is applied; providing at least one strip-shaped separator element (); introducing grooves () into the cathodic active material () around segmentation lines (S); generating a strip-shaped composite element () by applying the cathode element () onto the anode element (), with the interposition of the at least one separator element (); cutting the composite element () 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.
