Title (EN) GASKET AND DIAPHRAGM FOR ELECTROCHEMICAL CELL
(FR) JOINT D'ÉTANCHÉITÉ ET MEMBRANE POUR CELLULE ÉLECTROCHIMIQUE
Abstract:
(EN) An electrochemical cell includes a can configured to serve as one electric contact of the electrochemical cell, the can containing active materials, a diaphragm configured to serve as an opposite electric contact of the electrochemical cell,; and a gasket that is initially of generally cylindrical shape, the diaphragm positioned inside the gasket in an opening of the can wherein an outer edge of the can is crimped onto the gasket, the gasket having an inner periphery inside the can and an outer periphery outside the can, the outer periphery comprising leaves that after crimping extend along an outer surface of the diaphragm.
(FR) Cette invention concerne une cellule électrochimique, comprenant un bac configuré pour servir de premier contact électrique de la cellule électrochimique, le bac contenant des matériaux actifs, une membrane configurée pour servir de contact électrique opposé de la cellule électrochimique, et un joint d'étanchéité qui est initialement de forme généralement cylindrique, la membrane étant positionnée à l'intérieur du joint d'étanchéité dans une ouverture du bac dans laquelle un bord extérieur du bac est serti sur le joint d'étanchéité, le joint d'étanchéité présentant une périphérie interne à l'intérieur du bac et une périphérie externe à l'extérieur du bac, la périphérie externe comprenant des feuilles qui, après le sertissage, s'étendent le long d'une surface externe de la membrane.
