Document Type and Number:
WIPO Patent Application WO/2017/209219
Kind Code:
A1
Abstract:
Provided is a packaging material for batteries, which has high formability and enables the achievement of excellent continuous productivity of batteries. A packaging material for batteries, which is configured from a laminate that comprises at least a base layer, a barrier layer and a thermally fusible resin layer in this order, and wherein: the thermally fusible resin layer contains an amide-based lubricant and at least one agent selected from the group consisting of an antioxidant, a light stabilizer and a nucleator; and the absorption spectrum intensity ratio X = A/B as calculated using the absorption peak intensity A at the wavenumber of 1,650 cm-1 ascribed to C=O expansion/contraction vibration of the amide groups of the amide-based lubricant and the absorption peak intensity B at 1,460 cm-1 ascribed to -CH2- deformation vibration contained in the thermally fusible resin layer, said absorption peak intensity A and absorption peak intensity B being determined from the absorption spectrum obtained by spectrally dividing reflected light when the surface of the thermally fusible resin layer is irradiated with infrared light, is within the range of from 0.05 to 0.80 (inclusive).
