摘要： A welding apparatus is provided for a secondary battery having an electrode assembly with a center hole seated on a lower can. The welding apparatus includes a jig which includes an insertion portion that has a pipe shape and a diameter enabling entry into the center hole of the electrode assembly and a seating portion that has an enlarged diameter of a disk shape on an end of the insertion portion; and a laser irradiation apparatus to emit a laser beam into a hole of the insertion portion. When the electrode assembly is seated on the lower can such that an electrode tab of the electrode assembly is placed within the center hole, the laser irradiation apparatus performs a weld between the inner bottom surface of the lower can and the electrode tab after passing through the hole of the insertion portion of the jig.

摘要： A welding device welds an electrode tab protruding from an electrode assembly of a button-type battery to a can of the button-type battery. The welding device includes a base to support a bottom surface of the can when an inner surface of the can faces an upper side, and the electrode tab is in contact with the inner surface of the can; a jig on the base to fix the electrode tab on the base and having an opening hole through which a laser light for welding the electrode tab to the can passes; a laser irradiation device to irradiate the laser light to the opening hole when the jig fixes the electrode tab to the can; and four probes on the base or the jig. Two probes of the probes are connected to a power source, and the remaining two probes are connected to a voltmeter.

摘要： 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.
