Beschreibung
Zusammenfassung:	A method for bending an electrode tab according to an embodiment of the present invention for solving the above problem includes: a step of stacking an electrode and an separator to manufacture an electrode assembly; a step of connecting an electrode lead to the electrode tab protruding from the electrode assembly; a step of primarily bending the electrode tab while a bending block disposed at one side of the electrode tab moves in a first direction that is directed toward the other side of the electrode tab; and a step of secondarily bending the electrode tab while the bending block moves in a second direction different from the first direction.
