Claim:
1. A separator, comprising: a non-woven fabric substrate comprising fibers and having multiple pores between the fibers; and a polymer coating layer disposed on a part or the whole of the surface of strands of the fibers, wherein the polymer coating layer comprises a polymer having a tensile strength ranging from 80 MPa to 133 MPa, a tensile modulus ranging from 3,000 MPa to 7,800 MPa, and a flexural modulus ranging from 3,000 MPa to 7,300 MPa, wherein the polymer is selected from the group consisting of polyamide ether ketones (PAEK), polyimides (PI), polyphenylene sulfones (PPSU), polyphenylene ethers (PPE), polyether sulfones (PES), polyether ether ketones (PEEK), polybenzo imidazoles (PBI), polyether imides (PEI), polyamideimides (PAI), poly(p-phenylene-2,6-benzobisoxazoles), epoxy resins and a mixture thereof.
