The present invention relates to a pouch-shaped battery cell including a battery case made of a laminate sheet including an outer coating layer, a metal layer, and an inner adhesive layer, an electrode assembly received in the battery case, and a foam layer applied to an outer surface of an outer coating layer of any one of a first surface and a second surface of an electrode assembly receiving portion of the battery case. The foam layer buffers expansion in volume of the pouch-shaped battery cell, whereby it is possible to minimize deformation of the pouch-shaped battery cell and a battery module.
