ELECTRODE STACK TAPING METHOD, TAPING DEVICE, AND SECONDARY BATTERY

The present disclosure provides an electrode stack taping method, a taping device, and a secondary battery. The electrode stack taping method comprises a support tool driving step in which an upper support tool presses an upper side of an electrode stack and a lower support tool presses a lower side of the electrode stack; a unit head driving step in which an upper unit head applies tension to an upper tape by the upper tape away from the electrode stack while a side of the upper tape is attached to the upper side of the electrode stack, and a lower unit head applies tension to a lower tape by pulling the lower tape away from the electrode stack a side of the lower tape is attached to the lower side of the electrode stack The method may form a secondary battery in which salt extraction is prevented by increased adhesion and fixing force to a plurality of electrode plates.
