Novel Device for Notching and Secondary Battery Manufactured Using the Same

摘要

PURPOSE: A notching device is provided to stable form a notch in an electrode sheet in high rate, thereby remarkably improving productivity of notching process. CONSTITUTION: A notching device(100a) comprises a press(20a), and a drawing part. In process punching notches on an upper part and a lower part of an electrode sheet, the press punches notches on a site corresponding with the continuously transferred electrode sheet while moving toward rear side together with the electrode sheet, moving back to original position after punching, and repeating the same. The drawing parts are in rear side of the press based on direction the electrode sheet is supplied, and draw and transfer an electrode sheet of one pitch which is size corresponding with a unit electrode in accordance with the operation of the press.
