<p>PROBLEM TO BE SOLVED: To provide a heat-resistant synthetic resin microporous film which have excellent permeability to ions such as lithium ions and excellent heat resistance and does not cause the contamination of a production line, and to provide a method for producing the same.SOLUTION: There is provided a method for producing a heat-resistant synthetic resin microporous film in which a radical-polymerizable monomer containing a tri-functional or more acrylic monomer is coated on the surface of a synthetic resin microporous film and then the synthetic resin microporous film is subjected to plasma processing. According to the heat-resistant synthetic resin microporous film obtained by the method of the present invention, there can be provided a non-aqueous electrolyte secondary battery having high output and excellent safety.</p> |
