LAMINATED POROUS FILM, SEPARATOR FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

The purpose of the present invention is to provide a laminated porous film in which the adhesion between a polyolefin resin porous film that serves as a base film and a coating layer is high, and which has heat resistance and can exhibit excellent properties when used as a separator for a non-aqueous electrolyte secondary battery. The present invention provides a laminated porous film characterized in that a coating layer(layer II)containing a filler(a), a resin binder (b)and an adhesive agent (c)is laminated on at least one surface of a polyolefin resin porous film (layer I).
