摘要： The purpose of the present disclosure is to provide: a safer polyolefin microporous membrane; an electricity storage device separator, electricity storage device assembly kit, and electricity storage device using the polyolefin microporous membrane; and an electricity storage device. In one embodiment, the polyolefin microporous membrane comprises at least one of each of a layer A and a layer B, a polyolefin contained in at least one of the layer A and the layer B has one or more types of functional groups, and a crosslinked structure is formed by (1) the functional groups undergoing condensation reactions with each other, (2) the functional group reacting with a chemical substance inside the electricity storage device, or (3) the functional group reacting with a different type of functional group, after accommodation in the electricity storage device. In another embodiment, the polyolefin contained in at least one of the layer A and the layer B has one or more types of functional groups, and the functional groups include functional groups that undergo condensation reactions with each other inside the electricity storage device to form a crosslinked structure by siloxane bond.
