A battery separator for a lithium battery is disclosed. The separator has a microporous membrane and a coating thereon. The coating is made from a mixture of a gel forming polymer, a first solvent, and a second solvent. The first solvent is more volatile than the second solvent. The second solvent acts as a pore former for the gel-forming polymer.
