| 摘要 |
The present invention relates to a method of manufacturing an organic-inorganic hybrid porous separation membrane for a secondary battery and an organic-inorganic hybrid porous separation membrane manufactured by the same. The organic-inorganic hybrid porous separation membrane includes a porous polyolefin substrate and an active layer which is coated with an organic-inorganic binder polymer by reforming the active site of inorganic particles on the surface of the substrate with fatty acid of C6-C36 or oxidized wax. The porous separation membrane according to the present invention has strong adhesion with a substrate compared to an existing separation membrane, excellent ion conductivity and battery capacity retention rate properties. |
