Abstract: A separator for lithium-ion secondary batteries is characterized in that DPVDF is dip-coated on the separator and crosslinked. A material of the separator is selected from polyethylene (PE), polypropylene (PP), cellulose acetate (CA), polyvinylidene fluoride (PVDF), polyethersulfone (PES), or polyethylene terephthalate (PET). A method for manufacturing the separator includes: synthesizing polyvinylidene fluoride (DPVDF) including a double bond by dehydrochlorinating poly(vinylidene fluoride-co-chlorotrifluoroethylene [P(VDF-CTFE)]; coating a separator by dipping in a dipping solution formed by dissolving the DPVDF in an organic solvent; and crosslinking the DPVDF coated on the separator by performing a radical reaction by heat treatment.
