Side Sealing Device for Stacked Electrode Body, Secondary Battery Having Stacked Electrode Body, and Manufacturing Method Thereof

Abstract

A side sealing device for a stacked electrode body according to a preferred example of the present disclosure may comprise a seating part in which a stacked electrode body cross-laminated with positive electrodes, separators, and negative electrodes is seated; a press part pressurizing both sides of non-electrode sides of the stacked electrode body up and down to form sealing surfaces made of the separators so that ends of the separators come into contact with each other up and down to be in close contact therewith; and an adhesive application part applying an adhesive to the sealing surfaces in order to strengthen the sealing surfaces by imparting a fixing force between the separators forming the sealing surfaces.
