  • Multilayer separator with superior permeability
    Patent number: 9623640
    Abstract: Provided are a multilayer separator capable of improving interlayer peel strength and exhibiting excellent permeability due to a high degree of alignment, and a method of manufacturing the same. The method of manufacturing a multilayer separator includes: manufacturing a precursor film by co-extruding and molding a polypropylene based resin melt having a melt index (2.16 kg, 230° C.) of 0.3 to 5 g/10 min and a polyethylene based resin melt having a melt index (2.16 kg, 190° C.) of 0.1 to 1.5 g/10 min so as to be alternately laminated; and heat-treating and stretching the manufactured film, wherein a melt index ratio (A/B) of the polypropylene based resin melt (A) and polyethylene based resin melt (B) is 2 to 10.
