Title (EN) METHOD AND APPARATUS FOR PRODUCING A RECHARGEABLE BATTERY AND RECHARGEABLE BATTERY
(FR) PROCÉDÉ ET DISPOSITIF POUR LA FABRICATION D’UN ACCUMULATEUR ET ACCUMULATEUR
(DE) VERFAHREN UND VORRICHTUNG ZUR HERSTELLUNG EINES AKKUMULATORS UND AKKUMULATOR
Abstract:
(EN) In order to produce a rechargeable battery (1), a metal foil (3) is welded to a contact element (2) for the purpose of making electrical contact with an electrode of the rechargeable battery (1). Here, according to the invention, an edge region of the metal foil (2) is brought into contact with a first surface (4) of the contact element (2) and welded to the contact element (2) by applying a laser beam (6) to a second surface of the contact element (2), said second surface being averted from the first surface (4) of the contact element (2).
(FR) Pour la fabrication d’un accumulateur (1), une feuille métallique (3) est soudée à un élément de contact (2) pour la mise en contact d’une électrode de l’accumulateur (1). Conformément à l’invention, une zone de bordure de la feuille métallique (2) est mise en contact avec une première surface (4) de l’élément de contact (2) et soudée à l’élément de contact (2) par l’application d’un rayon laser (6) à une deuxième surface de l’élément de contact (2) opposée à la première surface (4) de l’élément de contact (2).
(DE) Zur Herstellung eines Akkumulators (1) wird zur Kontaktierung einer Elektrode des Akkumulators (1) eine Metallfolie (3) mit einem Kontaktelement (2) verschweißt. Hierbei wird erfindungsgemäß ein Randbereich der Metallfolie (2) mit einer ersten Fläche (4) des Kontaktelements (2) in Kontakt gebracht und durch die Beaufschlagung einer von der ersten Fläche (4) des Kontaktelements (2) abgewandten zweiten Fläche des Kontaktelements (2) mit einem Laserstrahl 6 mit dem Kontaktelement (2) verschweißt.
