Abstract
(EN)
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.
(FR)
La présente invention concerne un procédé de mesure de la teneur en humidité dans un séparateur d’accumulateur par chromatographie en phase gazeuse ayant un échantillonneur d’espace de tête. Le séparateur d’accumulateur peut être un séparateur SRS dans lequel des particules inorganiques et un polymère liant sont appliqués sur un substrat de polyoléfines.
