Abstract:
A composition for a non-aqueous secondary battery porous membrane including inorganic particles and a particulate polymer, wherein a volume-average particle diameter d0 of the inorganic particles is 0.1 μm or more and 1.0 μm or less, a weight ratio between the inorganic particles and the particulate polymer is within a range of 95:5 to 50:50, and a volume-average particle diameter d1 of the particulate polymer and the volume-average particle diameter d0 of the inorganic particles satisfy d1/d0>1; and a non-aqueous secondary battery including the same.
