Abstract: Disclosed in one or more embodiments is a notching device including a die configured to support an electrode, a first stripper configured to move toward the die, and configured to press a mixture portion of the electrode, a second stripper configured to move toward the die, and configured to press an uncoated portion of the electrode, and a pattern portion configured to move toward the die, and configured to form a pattern on the uncoated portion.

Abstract: A secondary battery electrode notching apparatus, including a die configured to support a secondary battery electrode including a composite portion coated with an electrode active material and an uncoated portion not coated with the electrode active material; a composite portion stripper configured to move toward the die and press the composite portion into close contact with the die; an uncoated portion stripper configured to move toward the die, press the uncoated portion into close contact with the die, and including an elastic pad formed of an elastic material and configured to elastically deform to make surface contact with the uncoated portion; and a punch configured to move toward the die and cut the uncoated portion so that scrap for disposal is formed from the uncoated portion.

Abstract: A pouch type rechargeable battery insulates a terrace side end (a metal portion) and tightly adheres an insulation tape by adhering the insulation tape while absorbing a position tolerance of a lead tab (or a tab seal) on a terrace. The pouch type rechargeable battery includes: an electrode assembly; a pouch forming a sealing portion at a side surface of a cell body receiving the electrode assembly by sealing an outer portion thereof, forming a terrace at the other side surface of the cell body, and sealing a lead tab connected to the electrode assembly by a tab seal to draw it out to the terrace; and an insulation tape that insulates the sealing portion to be adhered to the cell body and insulating the terrace. The insulation tape includes a cutting portion corresponding to and adhered to one side of the tab seal.
