摘要： A power storage device is constituted by a laminate including, in the stated order, at least a substrate layer, a barrier layer, and an inside layer. The inside layer is provided with an adhesive layer and a heat-sealing resin layer from the barrier layer side; and if dynamic viscoelasticity is measured by tension with respect to the inside layer, the growth rate at 80° C. is 8.0% or lower.

摘要： This exterior material for a power storage device is constituted of at least an outside layer, a barrier layer, and an inside layer, in that order from the outer side. The inside layer includes a compound represented by general formula (A). (In general formula (A), R11 and R12 each independently represent an alkyl group having 1 to 18 carbons, or a phenyl group that optionally has a substituent.)
