Abstract
An apparatus for cutting electrode sheets includes a conveyor and a laser device. The conveyor is configured to move an original sheet including an electrode portion and an ear portion extending from an edge of the electrode portion. The laser device is configured to move a laser to cut out a tab connected to the electrode portion from the ear portion of the original sheet. The laser device is also configured to move the laser from one edge of the electrode portion to another edge of the electrode portion to cut and separate a respective electrode sheet including the tab from the original sheet. The laser is configured to cut out the tab from the ear portion and cut and separate the respective electrode sheet including the tab from the original sheet as the conveyor is moving the original sheet.
