NOVELTY - A battery packaging material comprises an outer-layer side resin film layer (11), outer-layer side adhesive bond layer (12), metal foil layer (13), inner-layer side adhesive bond layer (14), and a heat-sealing layer (15), which are sequentially stacked. The outer-layer side adhesive bond layer comprises polyurethane adhesive comprising polyol component having number average molecular weight of 5000-50000 as a main ingredient, and a hardening agent comprising polyisocyanate component, where the polyol component is obtained by reacting polybasic acid component and polyhydric-alcohol component.    USE - Battery packaging material for use in a battery container of a battery (claimed) i.e. lithium ion battery. Can also be used as a laminated body for outdoor industrial application such as buildings and laminate that requires moldabilities, and for electrical storage and press through packaging materials such as capacitor, and as a steel plate, barrier material, roof material, solar-cell-panel material, window material, outdoor flooring material, illumination protective material and motor vehicle member.    ADVANTAGE - The battery packaging material has better moldability, high environmental tolerance, adhesive strength and reliability, and can be prevented from being ruptured at the time of shaping, and exhibits better performance at high-temperature and high-humidity for long period of time.    DETAILED DESCRIPTION - A battery packaging material comprises an outer-layer side resin film layer (11), outer-layer side adhesive bond layer (12), metal foil layer (13), inner-layer side adhesive bond layer (14), and a heat-sealing layer (15), which are sequentially stacked. The outer-layer side adhesive bond layer comprises polyurethane adhesive comprising polyol component having number average molecular weight of 5000-50000 as a main ingredient, and a hardening agent comprising polyisocyanate component, where the polyol component is obtained by reacting polybasic acid component and polyhydric-alcohol component, and 100 mol% of the polybasic acid component comprise 45-95 mol% aromatic polybasic acid component, and the equivalence ratio of isocyanate group in the polyisocyanate component is 0.5-10 with respect to the sum total of the hydroxyl group derived from the polyol and a carboxyl group. The polyol component comprises 85-99 wt.% polyester polyol and 1-15 wt.% trifunctional or more than trifunctional alcohol component in a sum total of 100 wt.%. An INDEPENDENT CLAIM is also included for a battery container.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a battery packaging material.
