Device and method for generating an electrode stack with flat electrode elements

A device for producing an electrode stack containing flat electrode elements, comprising:

• a stacking wheel, which is mounted to rotate about a stacking wheel axis and has a plurality of stacking wheel fingers, which define respective intermediate spaces for receiving the electrode elements;
• a wiper unit, which is designed to remove the electrode elements one after the other from the respective intermediate spaces through interaction with a rotational movement of the stacking wheel about the stacking wheel axis;
• a receiving unit, which is designed to successively receive the electrode elements removed from the intermediate spaces;
• wherein the receiving unit comprises a base structure, on which the electrode elements received in the receiving unit can be stacked;
• wherein the receiving unit furthermore comprises a delimiting element, which forms an end stop for the electrode elements received in the receiving unit and which is arranged statically in relation to the stacking wheel axis.

A method for producing an electrode stack containing flat electrode elements, comprising:

• providing a first electrode element;
• introducing the first electrode element into an intermediate space which is formed by stacking wheel fingers of a stacking wheel rotating about an axis of rotation;
• transporting the first electrode element using the stacking wheel;
• removing the first electrode element from the intermediate space;
• feeding the first electrode element into a receiving unit;
• delimiting a movement of the first electrode element by means of a delimiting element after said first electrode element has been fed into the receiving unit;
• providing a second electrode element;
• introducing the second electrode element into a further intermediate space, different from the intermediate space, which is formed by stacking wheel fingers of the stacking wheel;
• transporting the second electrode element using the stacking wheel;
• removing the second electrode element from the further intermediate space;
• feeding the second electrode element into the receiving unit so as therefore to produce an electrode stack, which is formed on a base structure of the receiving unit;
• delimiting a movement of the second electrode element by means of the delimiting element after said second electrode element has been fed into the receiving unit;
• wherein the delimiting element is arranged statically in relation to the axis of rotation and therefore forms an end stop for the first and second electrode elements fed into the receiving unit.
