Document Type and Number:
WIPO Patent Application WO/2011/162528
Kind Code:
A2
Abstract:
Disclosed is a porous nanoweb including first and second nanofilaments, which facilitates to perform heat resistance simultaneously with a shutdown function for preventing a battery explosion caused by an abnormal heat generation, and to realize small thickness and easy control of porosity, wherein, if the porous nanoweb is used as a battery separator for a secondary battery, it allow the good battery efficiency and good safety owing to the low resistance, the porous nanoweb comprising the first nanofilament having a melting temperature not more than 200℃ and the second nanofilament having a melting temperature not less than 210℃.
