Title (EN) LEAD TAB FOR A BATTERY TERMINAL
(FR) LANGUETTE DE CONNEXION POUR UNE BORNE DE BATTERIE
Abstract:
(EN) An electrochemical pouch cell includes a stacked or rolled arrangement of electrode plates disposed in a cell housing, and a lead tab that protrudes through the cell housing. The lead tab forms an electrical connection with the electrode plates within the cell and permits transfer of current out of the cell via an opening in a seal joint of the pouch cell housing. The lead tab has a configuration that improves reliability of the seal between the lead tab and the opening.
(FR) L'invention concerne une cellule de poche électrochimique comprenant un agencement empilé ou roulé de plaques d'électrode disposées dans un boîtier de cellule, et une languette de connexion qui fait saillie à travers le boîtier de cellule. La languette de connexion forme une connexion électrique avec les plaques d'électrode à l'intérieur de la cellule et permet le transfert de courant hors de la cellule par l'intermédiaire d'une ouverture dans un joint d'étanchéité du boîtier de cellule de poche. La languette de connexion présente une configuration qui améliore la fiabilité du joint d'étanchéité entre la languette de connexion et l'ouverture.
