Abstract
A packaging material for a power storage device of the present invention includes: a base layer having a first surface and a second surface, the first surface having at least a first adhesive layer, a metal foil layer, an anticorrosive treatment layer, a second adhesive layer, and a sealant layer laminated thereon in this order; and a base protective layer laminated on the second surface of the base layer, and formed containing at least one base resin selected from a group consisting of a polyester polyol and an acrylic polyol, each of which has a group having a hydroxyl group on a side chain, and a curing agent containing at least one of a biuret type and an isocyanurate type of isocyanate.
Claims18
A packaging material for a power storage device, comprising:
- a base layer having a first surface and a second surface, the first surface having at least a first adhesive layer, a metal foil layer, an anticorrosive treatment layer, a second adhesive layer, and a sealant layer laminated thereon in this order;
- and
- a base protective layer laminated on the second surface of the base layer, and formed containing a base resin consisting of a polyester polyol which has a group having a hydroxyl group on a side chain, and a curing agent containing at least one type of isocyanate selected from the group consisting of a biuret type of isocyanate, an isocyanurate type of isocyanate, and combinations thereof,
- wherein a ratio of the biuret type or the isocyanurate type to a total mass of the curing agent is in a range of about 10 mass percent or more
- wherein the base protective layer contains a filler having a mean particle size of the filler in a range of 0.2 μm or more to less than 3 μm and
- wherein a molar ratio of the isocyanate group contained in the isocyanate of the curing agent to the hydroxyl group contained in the polyol of the base resin (NCO/OH) is 1 to 20.
