Abstract
A heat-resistant separator composed of a non-woven fabric of high-melting resin, 1 to 20 &mgr;m in average fiber diameter, 5 to 300 g/m in basis weight, 1 to 200 cc/cm /sec in air permeability, and 0.01 to 1.0 mm in thickness, or a laminated heat-resistant separator composed of a laminate having a melt-blown, non-woven fabric layer of high-melting resin, 1 to 20 &mgr;m in average fiber diameter, 5 to 300 g/m in basis weight, 1 to 200 cc/cm /sec in air permeability, and 0.01 to 1.0 mm in thickness is more resistant to heat, and hence safer, and is suitable for batteries and electrical double-layer capacitors serviceable at high temperature.
