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.

Claims

1. 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 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 type of isocyanate selected from the group consisting of a biuret type of isocyanate, an isocyanurate type of isocyanate, and combinations thereof.

2. The packaging material for a power storage device of claim 1, wherein a ratio of the biuret type and the isocyanurate type to a total mass of the curing agent is about 10 mass percent or more.

3. The packaging material for a power storage device of claim 1, wherein a ratio of the biuret type to a total mass of the curing agent is in a range of about 10 mass percent or more to about 40 mass percent or less.

4. The packaging material for a power storage device of claim 1, wherein the curing agent contains only one of the biuret type or the isocyanurate type.

5. The packaging material for a power storage device of claim 1, wherein the curing agent contains both the biuret type and the isocyanurate type.

6. The packaging material for a power storage device of claim 1, wherein the isocyanate is 1,6-hexamethylene diisocyanate.

7. The packaging material for a power storage device of claim 1, wherein the base protective layer contains a filler.

8. The packaging material for a power storage device of claim 1, wherein the first adhesive layer contains a filler.
