| description | A method for manufacturing a secondary battery includes preparing a lower can having an accommodation part to accommodate an electrode assembly, and an upper cover covering an upper opening of the lower can; gripping an end of a lower can circumferential portion and an end of an upper cover circumferential portion at upper and lower portions using upper and lower jigs to weld the lower can circumferential portion extending outward from an edge of the accommodation part to the upper cover circumferential portion that is a circumferential area of the upper cover; and irradiating a laser onto a bonding portion at which the lower can circumferential portion and the upper cover circumferential portion are welded to each other. In the irradiating, a height of the accommodation part is higher than a height of the end of the lower can circumferential portion. |
