Abstract
A hybrid nonwoven separator having an inverted structure includes a nanofiber layer; and a substrate layer composed of a nonwoven fabric provided on both surfaces of the nanofiber layer to form an outermost layer. Because this separator is configured such that the substrate layer having a comparatively low coefficient of friction is disposed as the outermost layer thereof, structural defects generable in the course of manufacturing a separator can be prevented, thermal deformation of the nanofiber layer of the separator can be blocked, and also closure of pores of the nanofiber layer can be prevented thanks to pre-filtering, thus remarkably extending the lifespan of the separator.
