Beschreibung
Zusammenfassung:	The present invention relates to a method for manufacturing a secondary battery and an apparatus for manufacturing a secondary battery used for the same, and more particularly, to a method for manufacturing a secondary battery, which manufactures the secondary battery including a plurality of electrode tabs and an electrode lead, and an apparatus for manufacturing a secondary battery used for the method.The present invention provides a method for manufacturing a secondary battery, which includes a tab-lead stack welding process of performing welding on a tab-lead stack in which a plurality of electrode tabs and an electrode lead are stacked, to connect the electrode tabs to the electrode lead, and a tab-lead stack processing process of continuously pressing a welded portion of the tab-lead stack in a longitudinal direction to process the welded portion.
