POROUS COMPOSITE SEPARATOR AND MANUFACTURING METHOD THEREFOR

The present invention relates to a porous composite separator filled with a high heat-resistant porous polymer having nano-sized pores in addition to micro-sized wide pores formed among fibers of a porous support formed of the fibers, and to a manufacturing method therefor. The porous composite separator of the present invention has excellent strength, resistance to electrolyte swelling, and heat resistance and a minimized thickness change, and thus can provide a thin film type separator.
