Abstract: A battery packaging material including a laminate including at least a base material layer, a barrier layer, an adhesive layer, and a heat-sealable resin layer in this order, in which crushing of the adhesive layer is effectively prevented when the heat-sealable resin layer is heat-sealed with itself, and a high sealing strength is achieved in a high-temperature environment. The battery packaging material includes a laminate including at least a base material layer, a barrier layer, an adhesive layer, and a heat-sealable resin layer in this order, wherein the adhesive layer has a logarithmic decrement ΔE of 2.0 or less at 120° C. according to rigid-body pendulum measurement.

Abstract: A battery packaging material having excellent long-term adhesion of a barrier layer having an acid resistance film. The battery packaging material includes a laminate including at least a base material layer, a barrier layer, and a heat-sealable resin layer in this order, wherein the battery packaging material includes an acid resistance film on at least one surface of the barrier layer, and when the acid resistance film is analyzed using time-of-flight secondary ion mass spectrometry, a PPO3/CrPO4 ratio, which is the ratio of peak intensity PPO3 derived from PO3− to peak intensity PCrPO4 derived from CrPO4−, falls within a range of 6 to 120.
