| description | One aspect of the present invention provides a secondary battery which realizes high output of an electrode assembly by reducing electrical resistance at a connection portion between an uncoated portion and a lead tab. According to one embodiment of the present invention, the secondary battery includes: an electrode assembly wound by disposing a separator between electrodes; a lead tab connected to the electrode; and a case which accommodates the electrode assembly and through which the lead tab is drawn out. The lead tab includes a first tab which is formed to have a first width and a first thickness to be connected to the uncoated portion of the electrode, and a second tab which is formed to have a second width less than or equal to the first width and a second thickness greater than or equal to the first thickness.
본 발명의 일 측면은 무지부와 리드탭의 연결 부분에서 전기적인 저항을 감소시켜 전극 조립체의 고출력을 구현하는 이차 전지를 제공하는 것이다. 본 발명의 일 실시예에 따른 이차 전지는, 전극들 사이에 세퍼레이터를 배치하여 권취되는 전극 조립체, 상기 전극에 연결되는 리드탭, 및 상기 전극 조립체를 수용하고 상기 리드탭이 외부로 인출되는 케이스를 포함하며, 상기 리드탭은 제1폭과 제1두께로 형성되어 상기 전극의 무지부에 연결되는 제1탭, 및 상기 제1폭 이하의 제2폭과 상기 제1두께 이상의 제2두께로 형성되어 상기 제1탭에 연결되는 제2탭을 포함한다. |
