Zusammenfassung:Disclosed herein are battery separators that include a microporous membrane and a coating. The coating may comprise, consist, or consist essentially of polymeric components, inorganic components, or combinations thereof. The battery separators described herein are, among other things, thinner, stronger, and more wettable with electrolyte than some prior battery separators. The battery separators may be used in secondary or rechargeable batteries, including lithium ion batteries. The batteries may be used in vehicles or devices such as cell phones, tablets, laptops, and e-vehicles.
