Abstract
(EN) A battery cell according to an embodiment of the present invention comprises: a battery case in which an electrode assembly is mounted in an accommodation portion and which comprises a sealing portion having an outer circumference that is sealed; an electrode lead which is electrically connected to an electrode tab included in the electrode assembly and protrudes in the outer direction of the battery case via the sealing portion; and a lead film located on a portion, in at least one of the upper and lower portions of the electrode lead, corresponding to the sealing portion. A gas-discharge inducing portion is inserted in the lead film, and the sealing portion comprises a first sealing portion located on the gas-discharge guide portion and second sealing portions located at both sides of the first sealing portion. In addition, the width of the first sealing portion may be less than the width of the second sealing portion on the basis of the direction in which the electrode lead protrudes.
(FR) Un élément de batterie selon un mode de réalisation de la présente invention comprend : un compartiment de batterie dans lequel un ensemble électrode est monté dans une partie de réception et qui comprend une partie d'étanchéité ayant une circonférence externe qui est scellée ; un fil d'électrode qui est électriquement connecté à une languette d'électrode incluse dans l'ensemble électrode et fait saillie dans la direction extérieure du compartiment de batterie par l'intermédiaire de la partie d'étanchéité ; et un film conducteur situé sur une partie, dans au moins l'une des parties supérieure et inférieure du fil d'électrode, correspondant à la partie d'étanchéité. Une partie inductrice de décharge de gaz est insérée dans le film conducteur, et la partie d'étanchéité comprend une première partie d'étanchéité située sur la partie de guidage de décharge de gaz et des secondes parties d'étanchéité situées des deux côtés de la première partie d'étanchéité. De plus, la largeur de la première partie d'étanchéité peut être inférieure à la largeur de la seconde partie d'étanchéité sur la base de la direction dans laquelle le fil d'électrode fait saillie.
