Abstract

Pile électrochimique comprenant un boitier de pile présentant une extrémité ouverte qui est obturée par un élément d'étanchéité (10) présentant une ouverture (11) dans laquelle s'étend un élément métallique, caractérisée en ce qu'une matière extrudable (12)entoure la partie de l'élément métallique se trouvant dans cette ouverture, la matière extrudable étant en contact étanche avec la paroi de l'ouverture (11), une partie de cette matière extrudable étant exposée à la pression régnant à l'intérieur de la pile suivant une aire transversale qui est suffisamment grande pour permettre à cette matière de se déplacer en vue de permettre la libération de l'excès de pression interne.
