Document Type and Number:
WIPO Patent Application WO/2023/171807
Kind Code:
A1
Abstract:
The present invention provides an outer package material for power storage devices, the outer package material being configured from a multilayer body that comprises at least a surface coating layer, a base material layer, a barrier layer and a thermally fusible resin layer sequentially from the outer side, wherein the surface coating layer contains a resin and a filler. With respect to the outer surface of the surface coating layer, if the reflectance thereof is measured using a goniophotometer at the incident light angle of 60° for every 0.1° of the light reception angle, the ratio (A/B) of the maximum reflectance A in the light reception angle range from 55.0° to 65.0° to the maximum reflectance B in the light reception angle range from 70.0° to 80.0° is 3.50 or less.
