Abstract:
The present invention provides a nonaqueous electrolyte secondary battery separator which is excellent in cycle characteristic. The nonaqueous electrolyte secondary battery separator includes a polyolefin porous film in which a difference between (i) a porosity calculated from a continuous image which is formed so as to extend from a surface to an inside of the polyolefin porous film in a thickness direction and in which a void part and a resin part are shown at respective two gray levels and (ii) a porosity calculated from a thickness, a weight per unit area, and a real density of the polyolefin porous film is 4% to 20%.

Claim (Index 1):
A nonaqueous electrolyte secondary battery separator including a polyolefin porous film, wherein:\n a difference between an average porosity calculated from a continuous image of the polyolefin porous film and a porosity calculated based on a thickness, a weight per unit area, and a real density of the polyolefin porous film is 4% to 20%, the continuous image being obtained by FIB-SEM measurement with a magnification of 6500 times and image analysis, the continuous image having a size of 256 pix\u00d7256 pix along a surface of said nonaqueous electrolyte secondary battery separator where 1 pix is 19.2 nm, a thickness of the continuous image being equal to a thickness of said nonaqueous electrolyte secondary battery separator, the continuous image being formed so as to extend from the surface to an inside of said nonaqueous electrolyte secondary battery separator in a thickness direction, and, in the continuous image, a void part and a resin part of the polyolefin porous film being shown at respective two gray levels.
