Abstract: A method for forming a metal composite film for battery cells includes at least the following steps: (a) inserting the metal composite film into a forming apparatus having a recess; (b) fixing the metal composite film in place by closing a film holder; (c) preforming the metal composite film within the recess in a first direction; and (d) final forming of the metal composite film within the recess in a second direction.

Abstract: A battery cell having a layer stack including anode layers and corresponding cathode layers. The anode and cathode layers being stacked alternately one on top of the other. A separator layer is arranged between each anode and cathode layer. Anode or cathode conductor tracks are guided laterally out of the layer stack at least from some of the anode layers and/or some of the cathode layers at least on a first end face of the layer stack. The anode conductor tracks or the cathode conductor tracks being combined in a bundled manner and each contacted on the anode current collector or on the cathode current collector. The bundles of the anode or cathode conductor tracks are each passed between two folds, and insulation layers are held in position by a spring action of their particular folds against a pressure being applied indirectly by the first cover.

Abstract: A device and method for producing a thin-walled component, in particular a housing film for a pouch cell, from an initial part, comprising a first coil body, an electrical circuit for providing a pulsed electrical current, a die with a support facing the first coil body for the initial part to be reshaped, the support having the shape of the component to be produced, and a first separating device by which a first partial area can be at least partially separated from a second partial area of the initial part, it being possible for the initial part to be arranged between the first coil body and the die, to be accelerated by an electromagnetic force acting between the first coil body and the initial part towards the die and thereby to be deformed by the support and to be at least partially separated by the first separating device.

Abstract: A method for connecting a pre-sealing tape to a composite metal foil for pouch cells comprises at least the following steps: (a) creating a texture in at least a partial area of the composite metal foil; (b) applying a pre-sealing tape onto the composite metal foil, whereby the texture is at least partially covered by the pre-sealing tape; (c) connecting the pre-sealing tape to the composite metal foil to form a composite body; and (d) cutting the composite body to the predefined finished contour.

Abstract: A method for producing a battery cell includes at least the following steps: a) reshaping a first pouch foil into a first pouch half by means of a first molding device with a first recess; b) reshaping a second pouch foil into a second pouch foil by means of a second molding device with a second recess; c) inserting a cell stack into the first molding device and the first pouch half located therein; d) bringing together the first molding device and the second molding device with the second pouch half located therein; and e) at least partially connecting the first and second pouch halves to form a battery cell.

Abstract: A method for producing a component for storing electrical energy, said component comprising at least one cell stack for storing electrical energy and at least one contact element for making electrical contact with the at least one cell stack, has at least the following steps: a) arranging at least part of the at least one cell stack and the at least one contact element in a defined arrangement relative to one other in, or against a chamber that can be evacuated; b) evacuating at least some of the gas in the chamber; c) connecting the at least one cell stack and the at least one contact element together to form an electrically conductive connection by means of at least one laser beam introduced into the chamber.
