Title:
CROSS-LINKED POLYOLEFIN SEPARATOR AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/130412
Kind Code:
A1
Abstract:
Provided are: a cross-linked polyolefin separator comprising a cross-linked polyolefin having Si-O-Si cross-linking bonds, wherein inorganic particles are chemically bonded to the silicon (Si) of the Si-O-Si cross-linking bonds via oxygen (O); and a method for manufacturing the cross-linked polyolefin separator. The present invention provides a cross-linked polyolefin separator having a low resistance, a low air permeability and improved heat resistance.
