Abstract

A method for manufacturing a secondary battery includes: an accommodating process of accommodating an electrode assembly in a battery case so that an electrode lead connected to the electrode assembly protrudes to both sides of the outside of the battery case; a sealing process of sealing an outer circumferential surface of the battery case after the accommodating process; a coupling process of coupling a coupling clip to the electrode lead after the sealing process; and a transfer process of transferring the cell to a position for a next process after a gripper grips the coupling clip after the coupling process.
