The pressing device including first and second pressure plates configured to be arranged at opposite ends of the battery cell stack. Pressure elements are fixed to the first and second pressure plates and are made from a shape memory alloy and kept at a temperature greater than the final transformation temperature of the austenitic phase of the alloy, such that the pressing device is expanded with an increase in the thickness of the battery cells and is compressed with a decrease in the thickness of the battery cells.",
