BATTERY PACKAGING MATERIAL AND BATTERY
Document Type and Number:
WIPO Patent Application WO/2019/027021
Kind Code:
A1
Abstract:
Provided is a battery packaging material that: comprises a laminate that comprises, in order, at least a base material layer, a barrier layer, and a heat-fusible resin layer; and has excellent formability. This battery packaging material is configured from a laminate that comprises, in order, at least a base material layer, a barrier layer, and a heat-fusible resin layer. The laminate is no more than 100 μm thick, and, when the breaking energy of the laminate per unit length of 1 m is calculated from a measurement load (N/15 mm)—displacement curve measured by tensile test under the test conditions below, the sum X+Y of the breaking energy X in one direction that is orthogonal to the thickness direction of the laminate and the breaking energy Y in another direction that is orthogonal to the one direction and to the thickness direction of the laminate is at least 200 J. (Test conditions) Test speed: 50 mm/min. Width of test piece: 15 mm. Gauge length: 30 mm.
