Title
(EN) DEVICE FOR SEALING LITHIUM SECONDARY BATTERY ELECTROLYTE INJECTING HOLE
(FR) DISPOSITIF POUR FERMER DE MANIERE ETANCHE UN ORIFICE D'INJECTION D'ELECTROLYTE DANS UNE BATTERIE D'ACCUMULATEURS AU LITHIUM
Abstract
(EN)
A polar plate set (22) comprising an anode plate, a cathode plate, and a separator is inserted and installed inside a battery can (1) and a cap assembly (24) having an electrolyte injecting hole (24d) is mounted on an open part of the can so that the can interior is sealed. Furthermore, a rivet-like shaped sealing member (26) is affixed by being inserted in the electrolyte injecting hole (24d) and comes in contact with the cap assembly at an area surrounding the electrolyte injecting hole (24d).
(FR)
Un ensemble (22) plaque polaire comprenant une plaque anodique, une plaque cathodique et un séparateur est insérée et installée dans un logement (1) de batterie et un ensemble (24) couvercle possédant un orifice (24d) d'injection d'électrolyte est monté sur une partie ouverte du logement, de sorte que l'intérieur de ce dernier soit fermé hermétiquement. Par ailleurs, un élément (26) d'étanchéité en forme est inséré dans l'orifice (24d) d'injection d'électrolyte et vient en contact avec l'ensemble couvercle, dans une zone entourant l'orifice (24d) d'injection d'électrolyte.
