Abstract
This exterior material for a power storage device is configured from a laminate comprising at least a surface coating layer, a base layer, a barrier layer, and a heat sealing resin layer in order from the outside, and moreover is such that a logarithmic decrement ΔE at 60° C. in a rigid body pendulum measurement of the outside surface of the surface coating layer of the laminate is 0.12 or less.
Claims24
An exterior material for electrical storage devices comprising a laminate including at least a surface coating layer, a base material layer, a barrier layer, and a heat-sealable resin layer in this order from the outside, wherein a logarithmic decrement ΔE of an outer surface of the surface coating layer of the laminate is 0.120 or less at 60° C. in measurement with a rigid body pendulum.
An exterior material for electrical storage devices comprising a laminate including at least a surface coating layer, a base material layer, a barrier layer, and a heat-sealable resin layer in this order from the outside, wherein a logarithmic decrement ΔE of an outer surface of the surface coating layer of the laminate is 0.200 or less at 110° C. in measurement with a rigid body pendulum.
A method for manufacturing an exterior material for electrical storage devices, the method comprising the step of preparing a laminate in which at least a surface coating layer, a base material layer, a barrier layer, and a heat-sealable resin layer are laminated in this order from the outside, wherein
- a logarithmic decrement ΔE of an outer surface of the surface coating layer of the laminate is 0.120 or less at 60° C. in measurement with a rigid body pendulum.
