ELECTRICITY STORAGE DEVICE, ELECTRICITY STORAGE DEVICE CONTAINER, AND ELECTRICITY STORAGE DEVICE PACKAGING MATERIAL

摘要

A an electricity storage device according to the present invention including an electricity storage device packaging material, in the electricity storage device packaging material, from an outer layer thereof, at least an outer layer side resin film layer, an outer layer side adhesive layer, a metal foil layer, an inner layer side adhesive layer, and a heat seal layer being stacked, in which the inner layer side adhesive layer is a layer for bonding the metal foil layer with the heat seal layer, and is a layer obtained by performing a curing process for an adhesive compound including: a polyolefin resin (A) including a carboxyl group or an acid anhydride group; and an epoxy compound (B) including at least two epoxy groups and including at least one of an aromatic amino group and a heterocycle including a nitrogen atom as a heteroatom.

主权项

1. An electricity storage device comprising, at least, an electrolyte, an electrode, and an electricity storage device container,
wherein: the electricity storage device container comprises an electricity storage device packaging material, in the electricity storage device packaging material, from an outer layer thereof, at least an outer layer side resin film layer, an outer layer side adhesive layer, a metal foil layer, an inner layer side adhesive layer, and a heat seal layer being stacked; the heat seal layer is positioned in an inner surface of the electricity storage device container; parts of the heat seal layers of the electricity storage device packaging material are placed on each other and heat-sealed so that the electrolyte is hermetically encapsulated in the electricity storage device container; a terminal for an external connection extends from the electrode accommodated inside the electricity storage device container to the outside of the electricity storage device container, the terminal being sandwiched between the heat seal layers of the electricity storage device container, and wherein the inner layer side adhesive layer is a layer for bonding the metal foil layer with the heat seal layer, and is a layer obtained by performing a curing process for an adhesive compound comprising: a polyolefin resin (A) including a carboxyl group or an acid anhydride group; and an epoxy compound (B) including at least two epoxy groups and including at least one of an aromatic amino group and a heterocycle including a nitrogen atom as a heteroatom.
