摘要： The purpose of the present invention is to provide a packaging material for a battery capable of preventing the occurrence of cracks, pinholes and so forth during molding while having an excellent formability. In a packaging material for a battery constituted by a laminate body having at least a base material layer, a bonding layer, a metal layer and a sealant layer sequentially arranged in this order, the bonding layer satisfies at least two of the following properties (1) to (3), and thus prevents the occurrence of cracks, pinholes and so forth during molding, while having a remarkably excellent formability. (1) The hardness is 20 to 115 MPa when an indenter is pressed into the bonding layer by 5 µm from the cross-section of the laminate body using a nano-indenter. (2) The peak temperature is 10 to 60°C for the loss modulus peak that is acquired when a dynamic viscoelasticity is measured at a frequency of 1 Hz for the bonding layer. (3) I H /I M is 0.15 to 1.5, where an integral value of peak areas existing in 2800 to 3000 cm -1 is defined as I M , and an integral value of peak areas existing in 3100 to 3500 cm -1 is defined as I H , which are measured using an infrared absorption spectrum.

摘要： The present invention provides a condition for a substrate layer whereby a cell packaging material obtained by layering a substrate layer, a barrier layer, and a thermally fusible resin layer in this order is provided with excellent moldability. The substrate layer comprises a polyethylene terephthalate film, and the heat of fusion difference ΔH1-2 thereof determined by the method below is 6 J/g. In accordance with JIS K7122-2012, the film was heated from a temperature of 0°C to a temperature of 300°C using a differential scanning calorimeter under conditions of a temperature increase rate of 10°C/minute, and a heat of fusion H1 measured a first time was measured, and after measurement of this heat of fusion HI, the film was cooled from a temperature of 300°C to a temperature of 0°C at a temperature decrease rate of 10°C/minute, after which the film was heated from a temperature of 0°C to a temperature of 300°C under conditions of a temperature increase rate of 10°C/minute, and a heat of fusion H2 measured a second time was measured. The heat of fusion H2 was subtracted from the heat of fusion H1 to calculate the heat of fusion difference ΔH1-2.
