Abstract (en)
[origin: WO2021152080A1] The invention relates to a method for producing a component (1) for storing electrical energy, said component comprising at least one cell stack (2) for storing electrical energy and at least one contact element (3) for making electrical contact with the at least one cell stack (2), the method being characterised by at least the following steps: a) arranging at least part of the at least one cell stack (2) and the at least one contact element (3) in a defined arrangement relative to one other in, or against a chamber (4) that can be evacuated; b) evacuating at least some of the gas in the chamber (4); c) connecting the at least one cell stack (2) and the at least one contact element (3) together to form an electrically conductive connection by means of at least one laser beam (5) introduced into the chamber (4).
