摘要：
Methods for producing a battery separator are provided. The methods include applying a liquid precursor material to a substrate to generate a coating layer on the substrate. The liquid precursor material includes a polymer, and a first solvent. The methods also include precipitating the polymer from the liquid precursor material in the coating layer to form a polymer membrane, and drying the polymer membrane to generate a battery separator.
