US 9,865,846 B2 · Polymer battery module packaging sheet and a method of manufacturing the same

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.

Claims26

Dependent claims

A polymer battery module packaging sheet for forming an embossed type packaging comprising:

an oriented polyester film,
an oriented nylon film,
a first chemical conversion coating,
an aluminum layer,
a second chemical conversion coating,
an adhesive layer, and
a heat-sealable resin layer,
the above layers being provided in this order, wherein
the heat-sealable resin layer is formed of a cast polypropylene, and
wherein the first chemical conversion coating is formed on the aluminum layer on the side of the oriented nylon film, and configured to prevent separation of the oriented nylon film and the aluminum layer during an embossing process and heat-sealing.
