Abstract

A method for producing an electrochemical energy storage cell is provided. A current conductor, which is configured for electrically connecting an electrode stack to a cell terminal and has a contact arm, is positioned relative to the electrode stack such that an edge of the contact arm abuts a first lateral surface of a conductor arrangement that projects out of the electrode stack. The conductor arrangement is bent around the edge of the contact arm such that the first lateral surface of the conductor arrangement rests at least in part on a first contact arm lateral surface. The contact arm is supported on a second contact arm lateral surface opposite the first contact arm lateral surface. A contact pressure is exerted on the conductor arrangement resting at least in part on the first contact arm lateral surface, and the conductor arrangement is connected to the current conductor.
