Abstract:
1. A thee-dimensional electrode terminal of a battery constructed wholly in a plate shape and having an electrode assembly, which comprises electrodes, mounted in a pouch-shaped battery case, 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 mounted in the pouch-shaped battery case, the lower part being directly connected to one of the electrodes of the electrode assembly and having a plate shape and a thin thickness; wherein the upper part is integrally formed with the lower part and is thicker than the lower part, and the end and the side of a plate-shaped electrode terminal are bent such that the perpendicular surface is formed on the end of the electrode terminal while the electrode terminal has the predetermined thickness, whereby the electrode terminal is manufactured in a three-dimensional structure.
