Summary:The present invention provides a current collector which is applied to a cylindrical battery and electrically connects an electrode assembly and a battery housing. The current collector may comprise: a loop-shaped part for surrounding the circumference of the central axis of an electrode assembly so as to enable defining an opening area for exposing an electrode tab comprising a non-coated portion on one end portion of the electrode assembly; a tab coupling part extending toward the opening area from the inner side of the loop-shaped part adjacent to the opening area, and coupling to the electrode tab which is exposed through the opening area; and a housing coupling part coupled to a battery housing by extending toward the inner circumferential surface of the battery housing from the outer side of the loop-shaped part. La présente invention concerne un collecteur de courant qui est appliqué à une batterie cylindrique et connecte électriquement un ensemble électrode et un compartiment de batterie. Le collecteur de courant peut comprendre : une partie en forme de boucle pour entourer la circonférence de l'axe central d'un ensemble électrode de manière à permettre la définition d'une zone d'ouverture pour exposer une languette d'électrode comprenant une partie non revêtue sur une partie d'extrémité de l'ensemble électrode ; une partie de couplage de languette s'étendant vers la zone d'ouverture à partir du côté interne de la partie en forme de boucle adjacente à la zone d'ouverture, et un couplage à la languette d'électrode qui est exposée à travers la zone d'ouverture ; et une partie de couplage de boîtier couplée à un compartiment de batterie en s'étendant vers la surface circonférentielle intérieure du compartiment de batterie à partir du côté extérieur de la partie en forme de boucle. 본 발명은 원통형 배터리에 적용되는 전극조립체와 배터리 하우징 사이를 전기적으로 연결시키는 집전체를 제공한다. 상기 집전체는, 전극조립체의 일측 단부에서 무지부로 이루어진 전극탭을 노출시키는 개구 영역을 정의할 수 있도록 상기 전극조립체의 중심축 둘레를 에워싸는 루프 형상부; 상기 개구 영역과 인접하는 루프 형상부의 내측으로부터 상기 개구 영역을 향해 연장되고 상기 개구 영역을 통해 노출된 상기 전극탭과 결합하는 탭결합부; 및 상기 루프 형상부의 외측으로부터 상기 배터리 하우징의 내주면을 향해 연장되어 상기 배터리 하우징과 결합하는 하우징 결합부를 포함할 수 있다.
