摘要： [Problem] To provide a battery packaging material which can ensure safety even when the pressure or temperature increase in a battery has progressed persistently. [Solution] A battery packaging material which is made of a laminate comprising, as the essentials, a base material layer, a metal layer and a sealant layer in this order. When a product obtained by packaging a battery element with the packaging material in a hermetically sealed state through heat sealing is heated, the packaging material delaminates at least at a part of the interface between the metal layer and the outside surface of the sealant layer with the hermetically sealed state being kept, and thereafter works so as to make the product unsealed.

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： [Problem] To provide a highly insulative power-cell packaging material. [Solution] A power-cell packaging material comprising a layered body obtained by layering at least a substrate layer, a metal layer, an insulating layer, and a sealant layer, in this order. The insulating layer has a hardness in the range of 10-300 MPa, when measured by using a nanoindenter and pressing the indenter 5µm into the insulating layer from a cross-section of the layered body in the layering direction thereof.
