Abstract:
The invention relates to a method for producing an electrode stack from anodes (4) and cathodes (6) for a lithium-ion battery, in particular of an electrically driven motor vehicle, in which the cathodes (6) are provided in a first magazine (8) and are transported without grippers only in a first direction (R1) from the first magazine (8) into a chamber (12), in which the anodes (4) are provided in a second magazine (10) and are transported without grippers only in a second direction (R2) from the second magazine (10) into a chamber (12), wherein the cathodes (6) and anodes (4) are stacked alternately in the chamber (12), and in which the alternately stacked cathodes (6) and anodes (4) are aligned with one another, and pressed against one another, in the chamber (12). The invention also relates to an apparatus (16) for producing such an electrode stack (2).
