<p>Disclosed is a non-aqueous battery which employs a casing made of opposites sheets of at least-three-layer laminates, each comprising an inner thermoplastic resin layer, a middle metal foil layer and an outer electrically insulating material layer, wherein the pouchy casing has an elongated, hermetic adhesion area along a periphery of the pouchy casing in which adhesion area the opposite inner thermoplastic resin layers are melt-adhered to each other and the casing has terminal-withdrawal sites in the hermetic adhesion area, and wherein the casing satisfies any one or both of the following characteristics ( alpha ) and ( beta ): ( alpha ) the width of an elongated portion of the middle metal foil layer in the hermetic adhesion area of the casing, is at least ten times the thickness of an elongated portion of the inner thermoplastic resin layer in the hermetic adhesion area, and the elongated portion of the middle metal foil layer in the hermetic adhesion area is deficient in a peripheral portion thereof at least at portions thereof around the terminal-withdrawal sites; and ( beta ) the surface of the peripheral edge of the pouchy casing is treated for electric insulation at least at portions thereof around the terminal-withdrawal sites. <IMAGE> <IMAGE> <IMAGE></p> |
