Title (EN) SECONDARY BATTERY
(FR) BATTERIE SECONDAIRE
(KO) 이차전지
Abstract:
(EN) The present invention relates to a secondary battery which forms a multi-tap. In addition, the present invention comprises: a jelly roll in which an electrode and a separator are laminated to be crossed to each other, and which is wound around a center core; a plurality of multi-tap units extending from the electrode and formed in predetermined regions at the end of the jelly roll; a can member for receiving the jelly roll; and an insulating member, provided adjacent to the end, for insulating between the can member and the jelly roll, wherein the insulating member comprises: a center hole formed at the center thereof, the center hole being perforated so as to allow the center core to penetrate therethrough; and tap holes formed at the circumferential side of the center hole, tap holes being perforated to correspond to the plurality of multi-tap units so as to allow the plurality of multi-tap units to penetrate therethrough.
(FR) La présente invention concerne une batterie secondaire qui forme une multiprise. De plus, la présente invention comprend : un rouleau de gelée dans lequel une électrode et un séparateur sont stratifiés pour se croiser et qui est enroulé autour d'un noyau central ; une pluralité d'unités de multiprise s'étendant à partir de l'électrode et formées dans des régions prédéfinies à l'extrémité du rouleau de gelée ; un élément de boîte servant à recevoir le rouleau de gelée ; et un élément isolant adjacent à l'extrémité servant à l'isolation entre l'élément de boîte et le rouleau de gelée, l'élément isolant comprenant : un trou central formé en son centre, le trou central étant perforé de façon à ce qu'il puisse y pénétrer ; et des trous de prise formés sur le côté circonférentiel du trou central, des trous de prise étant perforés pour correspondre à la pluralité d'unités de multiprise de façon à ce qu'elles puissent y pénétrer.
(KO) 본 발명은 멀티 탭을 형성하는 이차전지에 관한 것이다. 또한, 본 발명은 전극과 분리막이 교차되게 적층되고, 중앙코어를 중심으로 권취된 젤리롤, 상기 전극으로부터 연장되고, 상기 젤리롤의 단부에서 소정의 영역에 복수 개 형성되는 멀티탭부, 상기 젤리롤을 수용하는 캔부재 및 상기 단부에 인접하게 마련되고, 상기 캔부재와 상기 젤리롤 사이를 절연하는 절연부재를 포함하고, 상기 절연부재에는, 중앙에 상기 중앙코어가 관통할 수 있도록 천공된 중앙홀 및 상기 중앙홀의 둘레 측에 상기 복수 개의 멀티탭부가 관통할 수 있도록 상기 복수 개의 멀티탭부에 대응하게 천공된 탭홀이 형성되어 있는 것을 특징으로 한다.
