Abstract: 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 in this order, the bonding layer satisfies at least two of the following properties (1) to (3). (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) IH/IM is 0.15 to 1.5, where an integral value of peak areas existing in 2800 to 3000 cm−1 is defined as IM, and an integral value of peak areas existing in 3100 to 3500 cm−1 is defined as IH.

Abstract: A power-cell packaging material including 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 5 μm into the insulating layer from a cross-section of the layered body in the layering direction thereof.

Abstract: Provided is a cell packaging material having a high insulating performance and durability. A cell packaging material comprising a layered body provided with at least a substrate layer, a metal layer, an adhesive layer, and a heat-fusible resin layer in the stated order. The adhesive layer has a resin composition that contains an acid-modified polyolefin and an epoxy resin. In probe displacement amount measurements involving the use of a thermal mechanical analyzer, when a probe is placed on the surface of the adhesive layer at an end part of the cell packaging material and the probe is heated from 40° C. to 220° C., the position of the probe does not drop in relation to the initial value.

Abstract: Presented is battery packaging material which is made of a laminate including, 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.

Abstract: A battery packaging material includes a laminate that includes at least a base material layer, a metal layer, an insulating layer, and a sealant layer laminated in this order. The insulating layer is formed of a resin composition containing a modified polyolefin resin modified with an unsaturated carboxylic acid or acid anhydride thereof and has a hardness, when measured by using a nanoindenter and pressing an indenter 5 μm into the insulating layer from a cross-section of the laminate in the laminating direction thereof, that ranges from 10 MPa to 300 MPa. In the sealant layer, an elastic modulus, when measured by using a nanoindenter and pressing an indenter 5 μm into the sealant layer from a cross-section of the laminate in the laminating direction thereof, ranges from 100 MPa to 1000 MPa.
