摘要:
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.

摘要:
Disclosed is a packaging material for forming an armor body for a battery, the armor body being adapted for use in such a manner that a battery body is inserted into the armor body and the peripheral edge of the armor body is then heat sealed for hermetic sealing, the packaging material being a laminate comprising at least a substrate layer, an adhesive layer, a barrier layer, a dry laminate layer, and a sealant layer, characterized in that at least the sealant layer comprises a low-fluidity polypropylene layer having low susceptibility to collapse upon exposure to heat and pressure at the time of heat sealing and a high-fluidity polypropylene layer having high susceptibility to collapse upon exposure to heat and pressure at the time of heat sealing, and the innermost layer is the high-fluidity polypropylene layer. This battery packaging material can impart moisture barrier properties and resistance to contents of the battery.
摘要:
A polymer battery module packaging material is a packaging laminated structure (10) including a base layer (11), a first adhesive resin layer (17b), a first chemically converted layer (16b), an aluminum layer (12), a second chemically converted layer (16a), a second adhesive resin layer (17a), a heat-sealable layer (14) and a liquid-paraffin layer (15). The second adhesive resin layer (17a) may be substituted by an acid-denatured polyolefin resin layer (13) formed by extrusion or an acid-denatured polyolefin resin layer (18) formed by coating. The heat-sealable layer (14) is formed of a polyolefin resin. The liquid paraffin layer (15) coating the heat-sealable layer (14) improves the emboss-formability of the polymer battery module packaging material.
