Abstract:
1. A three-dimensional electrode terminal of a battery constructed wholly in a plate shape and having an electrode assembly disposed in a pouch-shaped battery case and which comprises electrodes, the three-dimensional electrode terminal comprising: an upper part exposed from the pouch-shaped battery case, the upper part having a predetermined thickness, and a perpendicular surface formed on an upper end thereof; and a lower part disposed in the pouch-shaped battery case, the lower part directly connected to one of the electrodes of the electrode assembly and having a plate shape and a thin thickness relative to a thickness of the upper part; wherein the upper part is integrally formed with the lower part and is thicker than the lower part, and the predetermined thickness is a thickness allowing the electrical connection of the electrode terminal without artificially modifying the shape of the electrode terminal and allowing the electrode terminal to be formed generally in a three-dimensional structure, not in a plate-shaped structure.
