Claim:
1. A method for manufacturing a lithium-ion battery module, the method comprising: positioning an elastic plastic device between at least two cells of a prismatic cell stack of a battery module; and providing path-controlled compression of the at least two cells of the battery module, and of the elastic plastic device situated between the at least two cells; and providing a pressure band, a pressure plate and a cooling element; wherein the path-controlled compression is provided in a longitudinal direction L of the lithium-ion battery module and is carried out along a set path P up to a defined endpoint, and wherein the longitudinal direction L and the set path P are arranged parallel to each other, and wherein a plastic component of the elastic plastic device is configured to compensate for variation in a thickness of the cells as the cells age after the cells are manufactured, if at least two compressed cells become thicker.
