Abstract:
(EN) In order to solve the problems, a pouch-type secondary battery according to an embodiment of the present invention comprises: an electrode assembly having electrodes and a separator stacked therein, the electrodes including a cathode and an anode; a pouch-type battery case receiving the electrode assembly; an electrode tab connected to the electrodes and protruding from one side of the electrode assembly; a first electrode lead connected to the electrode tab at one end thereof; a second electrode lead, one end of which is connected to the other end of the first electrode lead and the other end of which protrudes to the outside of the battery case; and a connection part connecting the first electrode lead to the second electrode lead by attachment therebetween, wherein a first sloping surface is formed on at least one of the other end of the first electrode lead and the one end of the second electrode lead.
(FR) Afin de résoudre les problèmes, une batterie secondaire de type à poche selon un mode de réalisation de la présente invention comprend : un ensemble électrode ayant des électrodes et un séparateur empilé à l'intérieur de celui-ci, les électrodes comprenant une cathode et une anode ; un boîtier de batterie de type à poche recevant l'ensemble électrode ; une languette d'électrode connectée aux électrodes et faisant saillie d'un côté de l'ensemble électrode ; un premier fil d'électrode connecté à la languette d'électrode à une extrémité de celui-ci ; un second fil d'électrode, dont une extrémité est connectée à l'autre extrémité du premier fil d'électrode et dont l'autre extrémité fait saillie vers l'extérieur du boîtier de batterie ; et une partie de connexion connectant le premier conducteur d'électrode au second conducteur d'électrode par fixation entre ceux-ci, une première surface inclinée étant formée sur au moins une extrémité parmi l'autre extrémité du premier fil d'électrode et l'autre extrémité du second fil d'électrode.
