摘要:
The present invention provides a method for measuring moisture content in a separator of secondary battery by using a gas chromatograph equipped with a headspace sampler. The separator of secondary battery may be a safety reinforced separator (SRS) in which inorganic substance particles and a binder polymer are coated on a polyolefin substrate.
