    Abstract: Battery packaging material wherein a sheet-like laminated body is formed by sequentially stacking at least a base layer, metal layer, and sealant layer, the battery packaging material being equipped with substantially rectangular space that is formed to protrude from the sealant layer side toward the base layer side, and accommodates a battery element on the sealant layer side. In planar view from the base layer side view, a first and second curved sections are provided from the center portion toward the battery packaging material end parts, in a cross section in the thickness direction on a line connecting opposing corner parts protruding in a substantially rectangular shape. The thickness (a) of the metal layer at the first curved section, (c) of the metal layer at the second curved section, and (b) of the metal layer at the section located between the first and second curved sections, satisfy the following relationship a≥b>c or a≥c>b.

    Abstract: Provided is a battery packaging material that comprises a laminated body formed by sequentially stacking at least a base layer, a metal layer, and a sealant layer, and that has a thin overall thickness, and has excellent formability and piercing strength. This battery packaging material comprises a laminated body formed by sequentially stacking at least a base layer, a metal layer, and a sealant layer, with the overall thickness of the laminated body being 50-80 μm, and the ratio of the sum of the thicknesses of the base layer and the metal layer with respect to the overall thickness of the laminated body being in a range of 0.380-0.630.

    Abstract: A method for producing a battery packaging material, the method including the steps of: providing a battery packaging material including a laminate in which at least a base material layer, a metal layer, and a sealant layer containing a polyolefin resin are laminated in this order; and confirming that the intensity ratio X=P/Q is in the range of 0.05 to 0.80 where P is a peak intensity P at 1650 cm−1 originating from C═O stretching vibration of the amide group of an amide-based lubricant, and Q is a peak intensity Q at 1460 cm−1 originating from bending vibration of the group —CH2— of the polyolefin resin, each of which is measured from an absorption spectrum obtained by splitting reflected light in irradiation of the surface of the sealant layer with an infrared ray, and P/Q is a ratio of the peak intensity P to the peak intensity Q.
