Electrode assembly, manufacturing method thereof, and secondary battery

Abstract

The present disclosure relates to an electrode assembly in which a plurality of first electrode plates including electrode tabs, a plurality of second electrode plates including electrode tabs, and a separator interposed between each of the first electrode plates and each of the second electrode plates are arranged in a stacked manner. In the electrode assembly, electrode tabs of the same polarity are bend-formed so that the electrode tabs are gathered at the center of the stacking direction of the electrode assembly and protrude outward, and sub-tabs may be bonded on the bend-formed electrode tabs. In addition, the present disclosure may include a manufacturing method of an electrode assembly in which a pair of sub-tabs is respectively bonded on opposite sides of a bundle of electrode tabs that are gathered at the center of the stacking direction of the electrode assembly and protrude outward as described above.
