WIPO Patent Application WO/2024/048974

A1

Provided are a battery cell, and a battery module and a battery pack each including same, which are capable of preventing fracture of electrode tabs protruding from electrodes, preventing short circuits between electrode tabs and peripheral electrodes, and reducing the resistance between electrode tabs and electrode leads. The battery cell according to the present invention comprises: an electrode assembly including electrodes and an electrode tab stacking unit aligning electrode tabs protruding from the electrodes and vertically stacking the aligned electrode tabs; and an electrode lead including a lead coupling unit surrounding at least a portion of the electrode tab stacking unit, wherein the lead coupling unit is in contact with, while continuously surrounding, one of a top surface of the electrode tab stacking unit, a first side surface connected to the top surface, a second side surface opposite to the first side surface, and a bottom surface opposite to the top surface, and exposes the other one of the second side surface and the bottom surface opposite to the top surface.
