Abstract
Disclosed is a device for cutting an electrode sheet laminate wherein two or more continuous electrode sheets, in which an electrode active material is applied to one or both surfaces thereof, are laminated, to form a plurality of unit electrode laminates from the electrode sheet laminate, the device including a cutter to cut the electrode sheet laminate at a set position and thereby form unit electrode laminates, and two or more transport grippers arranged at the front of the cutter based on a feed direction of the electrode sheet laminate, the transport grippers drawing and transporting the electrode sheet laminate by one pitch, a size corresponding to the unit electrode laminate according to operation of the cutter, wherein while one of the transport grippers draws and transports the electrode sheet laminate, the remaining transport grippers move to a position for drawing.
