Pouch Type Battery Cell, And Method For Manufacturing Same

Abstract: In a pouch-type battery cell according to an embodiment of the present invention, an electrode assembly may be accommodated between a pair of cases comprising: a first resin layer forming the innermost layer; a second resin layer forming the outermost layer; and a metal layer laminated between the first resin layer and the second resin layer. The pouch-type battery cell may comprise: a cup part which is formed in at least one of the pair of cases and accommodates the electrode assembly; an insulating sealing part in which the first resin layers of the pair of cases are sealed with each other; a folded part in which an edge portion of one of the pair of cases is folded so as to surround an edge portion of the other case; and a metal sealing part which is formed in the folded part and in which the metal layers of the pair of cases are sealed with each other.
