摘要

#CMT# #/CMT# The composite foil (17) has layers arranged in mutual superposition. The layers comprise a base foil (10) made of plastic, a metal foil (12) and a functional plastics layer (14). A metal protective layer (13) is applied through a physical deposition process, such as vapor deposition processes or sputtering. A chromium layer with thickness of 0.1 to 1000 nanometers is arranged on the metal foil layer, or in the direction of the functional plastics layer or on the functional plastics layer. #CMT# : #/CMT# An independent claim is also included for a method for the production of plastics composite foil. #CMT#USE : #/CMT# Plastics composite foil for the sheathing of lithium ion polymer batteries and lithium polymer batteries (Claimed). #CMT#ADVANTAGE : #/CMT# The composite foil has layers arranged in mutual superposition, where layers comprise a base foil made of plastic, a metal foil and a functional plastic layer, thus prevents destruction of the aluminum foil by corrosion. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of a plastic composite foil. 10 : Base foil 11 : Adhesive layer 12 : Metal foil 13 : Metal protective layer 14 : Functional plastics layer 15 : Polyolefin 16 : Polyolefin layer 17 : Plastics composite foil #CMT#INORGANIC CHEMISTRY : #/CMT# The metal protective layer is a chromium layer, titanium layer or a zirconium layer. The metal foil is made of aluminum. The metal protective layer is applied in vacuum chamber for plasma treatment with oxygen plasma. #CMT#POLYMERS : #/CMT# The base foil is made of plastic, particularly polyamide layer and polyethylene terephthalate layer. The functional plastics layer is made of polypropylene or polyethylene terephthalate.
