Electrode-stacking wheel having an electrode-clamping element, corresponding electrode-stacking device, and method for producing an electrode stack

An electrode stacking wheel designed to receive and convey planar electrode elements, the electrode-stacking wheel comprising:

• a spindle designed to rotate the electrode stacking wheel;
• a plurality of stacking fingers, which are radial to the spindle and which are arranged circumferentially around the spindle;
• and
• a plurality of intermediate spaces, each of which is formed between the stacking fingers, wherein a respective intermediate space is designed to receive at least one of the electrode elements;
• wherein
• an electrode clamping element formed in each of the intermediate spaces,
• wherein the electrode clamping element is designed, in the clamping state, to apply clamping force to a main surface of one of the electrode elements and to press the respective electrode element against the respective stacking finger by means of the application of force.

A method for producing an electrode stack with planar electrode elements, in which the following steps are performed:

• a) providing an electrode element;
• b) rotating an electrode stacking wheel about a spindle;
• c) introducing the provided electrode element into an intermediate space formed by stacking fingers of the electrode stacking wheel;
• d) moving the electrode element thus introduced through the electrode stacking wheel rotating about the spindle;
• e) removing the moving electrode element from the intermediate space;
• and
• f) producing the electrode stack with the electrode element removed from the intermediate space,
• wherein
• a clamping force is applied to the electrode element, during its movement through the electrode stacking wheel, in a clamping position by means of an electrode clamping element.
