Abstract

A shaping apparatus for a pouch-shaped battery case includes a punch configured to press a laminate sheet in order to shape an electrode assembly receiving portion of the pouch-shaped battery case, a die in which an accommodation portion is formed having a size corresponding to the electrode assembly receiving portion, a holder configured to fix an outer periphery of the laminate sheet, and an electromagnetic field-generating means attached to the punch and configured to generate an electromagnetic field. A pouch-shaped battery case shaping process uses the shaping apparatus to manufacture the pouch-shaped battery case.
