METHOD OF MANUFACTURING CLADDING FOR LAMINATED BATTERY

In method for manufacturing an external cladding for a laminate battery according to the present invention, austenitic stainless steel foil 32 having a thermoplastic resin layer 30 on one of a front surface and a rear surface and a lubricating film 31 on the other surface is used as a material, the stainless steel foil 32 is disposed such that the surface provided with the thermoplastic resin layer 30 opposes a punch 42, and drawing is implemented on the stainless steel foil 32 without using lubricating oil in a condition where an annular region 32a of the stainless steel foil 32, which is contacted by a shoulder portion 42d of the punch 42, is set at a temperature of 20°C or lower, and an exterior region 32b on an exterior of the annular region 32a is set at a temperature between 40°C and 100°C.
