Title:
NOVEL DEVICE FOR NOTCHING AND SECONDARY BATTERY PRODUCED BY USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/074215
Kind Code:
A2
Abstract:
The present invention provides a device for notching, which is a device for notching an electrode sheet in intervals corresponding to the distance between unit electrodes, for manufacturing a plurality of unit electrodes from the electrode sheet which is continuous and is coated with electrode active material on one side or both sides, and comprises: a press for punching notches while moving backward with the electrode sheet to correspond to the position of the electrode sheet, which is continuously transferred, in a step of punching notches on the upper end and the lower end of the electrode sheet, the press repeating the motion of returning to the original position in the front after punching; and a receiving portion, which is located behind the press based on the direction in which the electrode sheet is supplied, for receiving and transferring the electrode sheet, one pitch at a time according to the movement of the press, the one pitch being a size which corresponds to the unit electrode.
