Abstract
Elément électrochimique pour batterie et batterie correspondante Cet élément électrochimique (6) pour batterie (2), comprenant une première électrode (8) d’une première polarité, un premier terminal (12) de la première polarité, une seconde électrode (10) d’une seconde polarité, un second terminal (14) de la seconde polarité, et une enveloppe (30) comprenant une première paroi (32) et une seconde paroi (34). La première paroi et la seconde paroi comprennent chacune un corps de base (50) en métal et une couche électriquement isolante (52). La couche électriquement isolante (52) comprend soit un revêtement en matière plastique, soit une couche issue d’un traitement de surface. Chacun des corps de base comprend un bord de corps de base (502, 504). Les bords des corps de base (50) sont reliés par un cordon de soudure (56) afin de former l’enveloppe (30). A l’emplacement du cordon de soudure (56), les corps de base sont exempts de la couche électriquement isolante. Figure pour l'abrégé : 2
