Title:
POLYAMIDE LAMINATED FILM FOR LITHIUM ION SECONDARY BATTERY EXTERIOR
Document Type and Number:
Japanese Patent JP2011175841
Kind Code:
A
Abstract:
To provide a polyamide laminated film for lithium ion secondary battery exterior by preventing the outstanding moldability of polyamide resin from being deteriorated and improving an acid resistance for hydrofluoric acid and resistance for electrolyte.
The polyamide laminated film for lithium ion secondary battery exterior includes at least a polyamide resin layer and an acid modified polyolefin resin (A) layer. In this case, the polyamide laminated film for lithium ion secondary battery exterior is characterized by having the acid modified polyolefin resin (A) contain 0.1 to 20 mass% of unsaturated carboxylic acid component and 50 to 98 mass% of unsaturated hydrocarbon component with a carbon number of 2 to 6.
