摘要： A separator with a heat resistant insulation layer includes a porous substrate layer and a heat resistant insulation layer formed on one surface or both surfaces of the porous substrate layer and containing inorganic particles and a binder. The ratio of tensile strength in MD direction×fracture strain in MD direction to the tensile strength in TD direction×fracture strain in RD direction is in a range from 0.3 to 20. A ratio of the unit mass of the heat resistant insulation layer to the unit mass of the porous substrate layer is in a range from 0.5 to 2.5. Accordingly, the separator with a heat resistant insulation layer can have improved resistance to an internal short-circuit (shorting resistance).

摘要： A separator with a heat-resistant insulation layer for an electric device includes a resin porous substrate and a heat-resistant insulation layer containing heat-resistant particles and a binder, the heat-resistant insulation layer being formed on at least one surface of the resin porous substrate. The heat-resistant particles contain alumina and a parameter X is 0.018 to 0.336. Parameter X is represented by X=Ca×Rzjis/D, wherein Cα is a ratio of the alumina, which occupies the heat-resistant particles, Rzjis is surface roughness of a surface of the heat-resistant insulation layer, the surface being opposite the resin porous substrate, and D is a thickness of the heat-resistant insulation layer.
