Abstract

본 발명은 통형의 케이스를 갖는 통형 전지 및 그 제조방법에 관한 것이다.The present invention relates to a cylindrical battery having a cylindrical case and a manufacturing method thereof.

본 발명에 따르면, 캡이 용접에 의해 케이스의 개구 부위에 결합되어 개구를 밀봉하므로, 실링을 위한 별도의 부재나 캡의 안착을 위한 케이스의 내항돌륜부 등을 마련하여야 할 필요가 없게 된다. 따라서, 밀봉작업이 단순화될 수 있으며, 케이스 내부의 공간에 전기요소가 충전될 수 있는 체적이 상대적으로 커지게 되어 통형 전지의 대용량화 또는 소형화를 이룰 수 있게 된다.According to the present invention, since the cap is coupled to the opening of the case by welding to seal the opening, there is no need to provide a separate member for sealing or an inner protrusion wheel part of the case for mounting the cap. Therefore, the sealing operation can be simplified, and the volume in which the electric element can be filled in the space inside the case becomes relatively large, thereby achieving a large capacity or a small size of the cylindrical battery.
