Abstract: In a packaging body provided with at least an inner layer composed of a thermal-adhesive polyolefin based resin and a barrier layer composed of a metal foil, in which metal terminals are sealed by the thermal-adhesive resin with unconnected ends of the metal terminals protruding outside, an adhesive sheet for sealing metal terminals of a flat electrochemical cell which is not only able to prevent a short circuit between the barrier layer and the metal terminals but high in a layer-to-layer adhesive strength and a low possibility of a reduction in battery performance to be caused due to invasion of moisture is provided. In the adhesive sheet for sealing a metal terminal part of a flat electrochemical cell according to the invention, a fibrous sheet or a porous sheet is covered by the inner layer and an acid-modified polyolefin based resin layer having adhesive properties.

Abstract: A polymer battery module packaging sheet includes, as essential components, a base layer (61), an aluminum layer (62), chemical conversion coatings (64a, 64b) coating the opposite surfaces of the aluminum layer (62), and an innermost layer (63). The chemical conversion coatings (64a, 64b) are formed by processing the opposite surfaces of the aluminum layer (62) by a phosphate treatment method. The base layer (61) and the innermost layer (63) are bonded to the chemical conversion coatings (64a, 64b) of the aluminum layer (62) with adhesive layers (65a, 65b), respectively.
