Title:
METHOD FOR MEASURING CONTENT OF MOISTURE IN SECONDARY BATTERY SEPARATOR
Document Type and Number:
WIPO Patent Application WO/2018/135777
Kind Code:
A1
Abstract:
The present invention provides a method for measuring a content of moisture in a secondary battery separator using gas chromatography having a headspace sampler. The secondary battery separator may be an SRS separator in which inorganic particles and a binder polymer are coated on a polyolefin substrate.
