Battery packaging material

A method for producing a battery packaging material which comprises a laminate including a coating layer, a base material layer, an adhesive layer, a barrier layer and a sealant layer in this order, the method comprising:

• a first step of laminating a base material layer and a barrier layer with an adhesive layer interposed therebetween to form a laminate including the base material layer, the adhesive layer and the barrier layer laminated in this order;
• and
• a second step of laminating a sealant layer on the barrier layer of the laminate obtained in the first step, wherein:
• before the first step, after the first step and before the second step, or after the second step, a resin composition containing a thermosetting resin and a curing accelerator is applied to a surface of the base material layer on a side opposite to a surface thereof on which the adhesive layer is laminated, and the resin composition is heated and cured to form a coating layer;
• and
• the thermosetting resin is a benzoguanamine resin.

• and
• the reactive slipping agent is selected from the group consisting of (i) block polymers having 1 to 3 functional groups that react with the thermosetting resin to be chemically bonded to the thermosetting resin, (ii) fluororesins in which an acrylate is graft-polymerized, and (iii) silicone-modified resins in which silicone is graft-polymerized and which have 1 to 3 functional groups that react with the thermosetting resin to be chemically bonded to the thermosetting resin.
