Title:
NOVEL DEVICE FOR CUTTING ELECTRODE SHEET AND SECONDARY BATTERY PRODUCED BY USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/074214
Kind Code:
A3
Abstract:
The present invention relates to a device for cutting, which is a device for cutting an electrode sheet stacked body for manufacturing a plurality of unit electrode stacked bodies from the electrode sheet stacked body having two or more electrode sheets which are continuous and are coated with electrode active material on one side or both sides, and comprises: a cutter for manufacturing the unit electrode stacked body by cutting the electrode sheet stacked body while the electrode sheet stacked body is fixed in a position; and two or more grippers, which are located in front the cutter 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 cutter, the one pitch being a size which corresponds to the unit electrode, wherein when one gripper from the grippers receives and transfers the electrode sheet, the other grippers move to a receiving position.
