Title:
COMPOSITE-TYPE STACKED CHEMICALLY-CROSSLINKED SEPARATOR
Document Type and Number:
WIPO Patent Application WO/2021/210317
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a safer polyolefin microporous film; a storage device separator, storage device assembly kit, and storage device using the polyolefin microporous film; and a storage device. In one embodiment, the polyolefin microporous film comprises at least one of each of an A layer and a B layer, polyolefin contained in at least one of the A layer and the B layer 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 storage device, or (3) the functional group reacting with a different type of functional group, after accommodation in the storage device. In another embodiment, the polyolefin contained in at least one of the A layer and the B layer has one or more types of functional groups, and the functional groups include functional groups that undergo condensation reactions with each other inside the storage device to form a crosslinked structure by siloxane bond.
