The separator substrate is a porous film including a polyolefin-containing polymer. The organic-inorganic composite porous coating layer includes a polymer resin particles and inorganic particles, in which each particle of the polymer resin particles includes a polyvinylidene fluoride (PVDF)-containing polymer and an acrylic polymer, and the PVDF-containing polymer has a Hansen solubility parameter (HSP) value of 13 or less and 1 or more.",
