  • Apparatus and Method for Bending Electrode Tab
    Publication number: 20220416374
    Abstract: A method for bending an electrode tab is disclosed herein. The method may include: stacking an electrode and an separator to form an electrode assembly, connecting an electrode lead to an electrode tab protruding from the electrode assembly, primarily bending the electrode tab by moving a bending block disposed at one side of the electrode tab in a first direction directed toward the other side of the electrode tab, and secondarily bending the electrode tab by moving the bending block in a second direction different from the first direction.

  • Pouch for secondary battery and die for forming the same
    Patent number: 10971705
    Abstract: Provided are a pouch for a secondary battery, which is capable of minimizing a folded area of a bridge part of the pouch that is manufactured by folding two accommodation parts to overlap each other, and a die for forming the pouch for the secondary battery. The pouch for the secondary battery includes a lower accommodation part accommodating an electrode assembly therein, an upper accommodation part covering an opening of the lower accommodation part, and a bridge part connecting the lower accommodation part to the upper accommodation part. When the lower accommodation part and the upper accommodation part are unfolded, a height of the bridge part, which is measured from a bottom surface of the lower accommodation part, is lower than that of the lower accommodation part, which is measured from the bottom surface of the lower accommodation part.
