Abstract
The invention relates to a double aluminum layer type aluminum plastic film applied to a polymer lithium ion battery. The aluminum plastic film comprises a polypropylene layer, an adhesion layer, an aluminum foil layer, an adhesion layer, a resin film layer, an adhesion layer, an aluminum foil layer, an adhesion layer and a resin film layer, wherein from interior to exterior the polypropylene layer, the adhesion layer, the aluminum foil layer, the adhesion layer, the resin film layer, the adhesion layer, the aluminum foil layer, the adhesion layer and the resin film layer are sequentially arranged in the aluminum plastic film. According to the double aluminum layer type aluminum plastic film applied to the polymer lithium ion battery, an aluminum foil and resin composition film layer is additionally arranged on the outer layer of the inner-layer aluminum foil, so that the barrier property and the wear resistance of the inner-layer aluminum foil can be effectively improved; the double aluminum layer type aluminum plastic film is a high-barrier aluminum plastic film and can be applied to the polymer lithium ion battery.
