Energy Storage Cell, Production Method and Apparatus for Carrying Out Such a Method

A method for producing electrochemical energy storage cells, the method comprising:

• a positioning step in which a current conductor, which is adapted for electrical connection of an electrode stack to a cell terminal and comprises a contact arm, is positioned relative to the electrode stack such that an edge of the contact arm bears on a first side face of a conductor arrangement of the electrode stack, wherein the conductor arrangement protrudes from the electrode stack;
• a bending step in which the conductor arrangement is bent around the edge of the contact arm such that the first side face of the conductor arrangement bears at least in sections on a first contact arm side face;
• a supporting step in which the contact arm is supported on a second contact arm side face lying opposite the first contact arm side face;
• a pressing step in which a pressing force is exerted on the conductor arrangement bearing at least in sections on the first contact arm side face;
• and
• a connecting step in which the conductor arrangement is connected to the current conductor.
