摘要（英）：

As a battery separator is laminated on one surface modified porous layer comprising a fluorine-based resin and inorganic particles or crosslinked polymer particles, the polyolefin microporous membrane of thickness less than 16㎛, the polyolefin microporous membrane of (a) a shutdown temperature of less than 135 ℃, (b ) dumping resistance change rate is ^{1 × 10 4 sec / 100cc /} ℃ or more, and cells that satisfy the equation 1 and the equation 2, the separator, and a method for producing the battery separator.
0.01≤absT (1200) ≤0.30 ··· Equation 1
absT (1200): Modification of the polyolefin porous layer microporous polyolefin microporous membrane infrared spectroscopic measurement of the absorbance per 10㎛ thickness of the absorbent which has a peak in the vicinity of 1,200cm ^-1 by the (transmitting method) when peeled from the membrane 0.001≤absR ( 1200) ≤0.030 ··· equation 2
absR (1200): 1, 200cm -1 near the maximum absorbance peak by infrared spectrometry (reflection method) of the polyolefin microporous membrane in a half-modified porous layer surface side
Consequently, the present invention has the adhesion to the electrode, and excellent shutdown performance, the electrolyte solution permeability, and provides a method for producing a battery separator and a battery separator suitable for high-capacity batteries.
