An electrochemical battery cell with an improved thermoplastic sealing member. The seal member is made from a thermoplastic resin comprising polyphthalamide or impact modified polyphenylene sulfide. The seal member provides an effective seal vent over a broad temperature range and has a low electrolyte vapor transmission rate.

Cette invention concerne une cellule de batterie électrochimique comprenant un élément d'étanchéité thermoplastique amélioré. L'élément de joint est constitué d'une résine thermoplastique comprenant un polyphtalamide ou un sulfure de polyphénylène antichoc. L'élément de joint permet d'obtenir un évent de joint efficace sur une vaste gamme de température et présente un faible taux de transmission de vapeur électrolytique.
