Abstract
An electrode assembly has a structure in which a plurality of electrodes, from each of which an electrode tab protrudes, is stacked, wherein the electrodes are coupled to each other by welding the electrode tabs to each other, the electrode tabs are coupled to an electrode lead, the electrode lead wraps the electrode tabs by including an electrode lead main body with a first surface coupled to the upper surface of the electrode tabs, a second surface bent at a first bent portion in a state of being connected to the first surface so as to be coupled to a lower surface of the electrode tabs, and a third surface bent at a second bent portion in a state of being connected to the second surface and configured to be withdrawn outside a battery case, and the electrode tabs are coupled to the electrode lead by clinching.
