Abstract

A clamping system for fixing in position a stack of electrode foils for the downstream manufacturing of battery cells, including a base plate, a pressure plate, at least two clamping elements and a receiving region for receiving the stack between the base plate and the pressure plate, the clamping elements clamping together the base plate and the pressure plate in a way that enables the electrode foils to be fixed in position in the receiving region, the clamping elements being located in the edge regions of the respective long sides of the plates outside of the receiving region, and/or the base plate and the pressure plate each having a plurality of, however, at least two, attachment points for connecting the clamping system to apparatuses of the downstream battery cell production in that the attachment points of a particular plate are differently embodied in the shape or size thereof.
