Manufacturing Device Of Secondary Battery And Manufacturing Method Of Secondary Battery

Abstract: A device for manufacturing a secondary battery according to an embodiment of the present invention is a device for manufacturing a secondary battery comprising multiple electrodes and separators stacked alternately, electrode tabs provided on ends of the multiple electrodes, and an electrode lead coupled to the electrode tabs. The device comprises: an upper holding die and a lower holding die for holding the electrode lead, with the electrode lead interposed therebetween; a lower molding die disposed to be spaced apart from the lower holding die toward the outer end of the electrode lead; and multiple upper molding dies disposed to be spaced apart from the upper holding die toward an end of the electrode lead. The multiple upper molding dies comprise a first upper molding die for holding the electrode lead, and a second upper molding die for forming first and second bending portions. The first upper molding die and the second upper molding die are separated from each other, and are successively disposed in a direction from an electrode assembly toward an end of the electrode lead.
