Abstract
(EN) A secondary battery according to an embodiment of the present invention comprises: an electrode assembly formed by disposing a first and a second electrode, each having a coated part and uncoated part tabs, on both sides of a separator; a case for receiving the electrode assembly; a cap plate coupled to an opening of the case and electrically connected to the uncoated part tabs of the second electrode; a first electrode terminal installed in the cap plate while being electrically insulated therefrom, and connected to the uncoated part tabs of the first electrode; a second electrode terminal bonded to the cap plate with an insulating film interposed therebetween; and an overcharge safety device electrically connecting the cap plate and the second electrode terminal, and electrically disconnecting the cap plate and the second electrode terminal when the battery is overcharged.
(FR) Une batterie secondaire selon un mode de réalisation de la présente invention comprend : un ensemble d'électrodes formé en disposant une première et une seconde électrode, chacune ayant une partie revêtue et des pattes de parties non revêtues, des deux côtés d'un séparateur ; un boîtier permettant de recevoir l'ensemble d'électrodes ; une plaque servant de capot couplée à une ouverture du boîtier et connectée électriquement aux pattes de parties non revêtues de la seconde électrode ; une première borne d'électrode installée dans la plaque servant de capot tout en étant isolée électriquement de celle-ci, et connectée aux pattes de parties non revêtues de la première électrode ; une seconde borne d'électrode liée à la plaque servant de capot à l'aide d'un film isolant interposé entre celles-ci ; et un dispositif de sécurité contre les surcharges connectant électriquement la plaque servant de capot et la seconde borne d'électrode, et déconnectant électriquement la plaque servant de capot et la seconde borne d'électrode lorsque la batterie est surchargée.
