An electrochemical battery cell with an electrical lead for electrical contact between one of the cell's electrodes and the side of the cell container. A portion of the lead, disposed between the electrode assembly and the side wall of the container, includes an initially non-planar shape that is in a partially deformed, compressed configuration within the cell to bias the lead against the internal surface of the side wall of the container, thereby applying sufficient force to provide good electrical contact between the electrode and the container. The initially non-planar shape can include one or more V-shaped or arc-shaped grooves, and the grooves can be disposed parallel to a longitudinal axis of the electrode assembly. Also disclosed is a process for making such a cell.

L'invention concerne un élément de batterie électrochimique à conducteur électrique conçu pour un contact électrique entre une des électrodes de la cellule et le côté du contenant de cellule. Une partie du conducteur, placée entre l'ensemble électrode et la paroi latérale du contenant, comporte une forme initialement non plane qui est dans une configuration partiellement déformée et comprimée à l'intérieur de la cellule de façon à polariser le conducteur contre la surface interne de la paroi latérale du contenant. Une force suffisante s'exerce ainsi pour produire un bon contact électrique entre l'électrode et le contenant. La forme initialement non plane peut comporter au moins une rainure en V ou curviligne, ces rainures pouvant être disposées parallèles à un axe longitudinal de l'ensemble électrode. L'invention concerne enfin un procédé de fabrication d'une telle cellule.
