Abstract
A separator includes a planar non-woven fabric substrate having a plurality of pores, and a porous coating layer provided on at least one surface of the non-woven fabric substrate and made of a mixture of a plurality of inorganic particles and a binder polymer, wherein the non-woven fabric substrate is made of superfine fibers having an average thickness of 0.5 to 10 μm, and wherein, among the pores in the non-woven fabric substrate, pores having a wide diameter of 0.1 to 70 μm are 50% or above of the entire pores. The above separator having the porous coating layer may generate the generation of leak current without increasing a loading weight of the porous coating layer since the non-woven fabric substrate having a controlled pore side by using superfine fibers of a predetermined thickness is used.
