| description | An embodiment of the present invention relates to a cylindrical secondary battery, comprising: a cylindrical can; an electrode assembly on which a first electrode plate, a second electrode plate, and a separator are wound, and which is accommodated in the can; and a cap assembly insulated from the can, electrically connected to the electrode assembly, and having a degassing hole formed therethrough to communicate with the inside of the can. According to an embodiment of the present invention, a degassing function is applied to remove gas generated before product shipment, thereby reducing deformation of the can and cap assembly. In addition, degradation of secondary battery performance can be reduced by preventing swelling of the electrode assembly due to internal gas generation.
본 발명의 실시 예는 원통형 이차전지에 관한 것으로, 원통형 이차전지는 원통형의 캔; 제1 전극판 및 제2 전극판, 세퍼레이터가 권취되며, 상기 캔에 수용되는 전극 조립체; 및 상기 캔과는 절연되고 상기 전극 조립체와는 전기적으로 연결되며, 상기 캔 내부와 연통되도록 홀이 관통 형성된 캡 어셈블리를 포함할 수 있다. 본 발명의 실시 예에 따르면, 디게싱(degassing) 기능이 적용되어 제품 출하 전 발생한 가스 제거가 가능하므로 캔 및 캡 어셈블리의 변형을 감소시킬 수 있다. 또한, 내부 가스 발생에 따른 전극 조립체의 스웰링 발생을 방지하여 이차전지의 성능 저하를 줄일 수 있다. |
