Beschreibung
Zusammenfassung:	A method of manufacturing a secondary battery includes: ultrasonic-welding a first electrode plate of an electrode assembly and a first electrode tab to each other by using a first horn including a first protruding tip; ultrasonic-welding a second electrode plate of the electrode assembly and a second electrode tab to each other by using a second horn including a second protruding tip, the second protruding tip having a positioning direction different from a positioning direction of the first protruding tip; and preparing the electrode assembly by arranging a separator between the first and second electrode plates.
