Method for producing an electrode stack, and stacking device

A method for producing an electrode stack with flat electrode elements, in which the following steps are carried out:

• a) providing a first electrode element;
• b) inserting the first electrode element into an intermediate space which is formed by stacking fingers of at least one stacking wheel which rotates about a rotation axis;
• c) transporting the first electrode element with the stacking wheel;
• d) removing the first electrode element from the intermediate space;
• e) arranging the first electrode element in a stacking position;
• f) providing a second electrode element;
• g) inserting the second electrode element into a further intermediate space which is different from the intermediate space and is formed by stacking fingers of the stacking wheel;
• h) removing the second electrode element from the further intermediate space;
• and
• i) arranging the second electrode element in the stacking position and producing the electrode stack,
• wherein
• at least the first electrode element is moved to a lateral target position by at least one movable alignment element.

A stacking device which is designed to produce an electrode stack with flat electrode elements, having:

• a provision unit which is designed to provide an electrode element;
• at least one stacking wheel having a rotation axis and multiple stacking fingers arranged radially to the rotation axis,
• wherein the stacking fingers form multiple intermediate spaces which are each designed to receive an electrode element for transport;
• and
• a stacking position which is designed for the arrangement of the electrode stack,
• wherein the stacking device has a movable alignment element which is designed to move the electrode elements to a lateral target position.
