Title:
EXTERIOR MATERIAL FOR POWER STORAGE DEVICE, POWER STORAGE DEVICE, AND METHOD FOR MANUFACTURING EXTERIOR MATERIAL FOR POWER STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/059665
Kind Code:
A1
Abstract:
An exterior material (1) for a power storage device is provided with a base material layer (3), a metal layer (2), and a sealant layer (4), wherein the value of F defined by the following expression 1 is greater than 0.
(1): F = -6.0 – 0.13a – 0.51b + 0.000073c – 3.9d + 0.91e + 1.5f – 3.9g + 0.027h + 2.1i + 2.3j
where a to j are, respectively, on an inside surface (1a) of the exterior material (1): the arithmetic mean curvature Spc (unit: mm-1) of peaks; the five-point peak height S5p (μm); the smooth-rough crossover SRC (μm2); the areal fractal complexity Safc (non-dimensional); the level difference Sk (μm) of a core part; the pole height Sxp (μm); the root mean square slope Sdr (%); the minimum self-correlation length Sal (μm); the spatial volume Vvc (mL/m2) of the core part; and the volume Vmc (mL/m2) of the core part.
