Abstract
The present invention provides a battery cell including: an electrode assembly configured of a positive electrode, a negative electrode, and a separation membrane; and a battery case in which a sealing surplus part is formed at an external circumference in a state that the electrode assembly is built in a receiving unit, wherein the battery case is formed of a sheet-shaped structure having a first surface and a second surface opposite to the first surface, an electrode terminal of the sheet-shaped structure is protruded through one side sealing surplus part of the battery case, and the electrode terminal is in contact with one surface or the other surface opposite to the one surface of the sealing surplus part in a state that the electrode terminal is bent in the first surface direction or the second surface direction of the battery case at the protrude part.
