Title
(EN) SECONDARY CELL FOR A TRACTION BATTERY AND METHOD FOR MANUFACTURING A SECONDARY CELL
(FR) CELLULE SECONDAIRE POUR UNE BATTERIE DE TRACTION ET PROCÉDÉ DE FABRICATION D'UNE CELLULE SECONDAIRE
Abstract
(EN) The invention relates to a secondary cell (1) for a traction battery of a vehicle, comprising: a prismatic casing (2) comprising a case part (3) having an aperture (4) at one side and a cap part (5) being at least indirectly connected with this side of the case part (3); and at least one electrochemical cell (6) contained within the casing (2) and comprising at least one anode current collector (7) electrically connected with an anode terminal of the secondary cell (1) and at least one cathode current collector (8) electrically connected with a cathode terminal of the secondary cell (1), wherein both the anode current collector (7) and the cathode current collector (8) are arranged on one side of the electrochemical cell (6) facing the cap part (5), and at least one current collector (7, 8) is welded to the respective terminal or is welded to at least one electrically conductive element (9, 3) being welded to the respective terminal.
(FR) L'invention concerne une cellule secondaire (1) pour une batterie de traction d'un véhicule, comprenant : un boîtier prismatique (2) comprenant une partie boîtier (3) ayant une ouverture (4) sur un côté et une partie de couvercle (5) étant au moins indirectement connectée à ce côté de la partie de boîtier (3); et au moins une cellule électrochimique (6) contenue à l'intérieur du boîtier (2) et comprenant au moins un collecteur de courant d'anode (7) connecté électriquement à une borne d'anode de la cellule secondaire (1) et au moins un collecteur de courant de cathode (8) connecté électriquement à une borne de cathode de la cellule secondaire (1), le collecteur de courant d'anode (7) et le collecteur de courant de cathode (8) étant disposés sur un côté de la cellule électrochimique (6) faisant face à la partie de couvercle (5), et au moins un collecteur de courant (7, 8) étant soudé à la borne respective ou étant soudé à au moins un élément électro-conducteur (9, 3) soudé à la borne respective.
