Title (EN) IMPROVED MICROLAYER MEMBRANES, IMPROVED BATTERY SEPARATORS, AND RELATED METHODS
(FR) MEMBRANES MICROCOUCHES AMÉLIORÉES, SÉPARATEURS DE BATTERIE AMÉLIORÉS ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) Described herein is a multilayer microporous film or membrane that may exhibit improved properties, including improved dielectric break down and strength, compared to prior monolayer or tri-layer microporous membranes of the same thickness. The preferred multilayer microporous membrane comprises microlayers and one or more lamination barriers. Also disclosed is a battery separator or battery comprising one or more of the multilayer microporous films or membranes. The inventive battery and battery separator is preferably safer and more robust than batteries and battery separators using prior monolayer and tri-layer microporous membranes. Also, described herein is a method for making the multilayer microporous separators, membranes or films described herein.
(FR) L'invention concerne une membrane ou film microporeux multicouche pouvant présenter des propriétés améliorées, notamment une rupture et une résistante diélectriques améliorées, par rapport à des membranes microporeuses monocouches ou tri-couches de la même épaisseur des antériorités. La membrane microporeuse multicouche préférée selon l'invention comprend des microcouches et au moins une barrière de stratification. L'invention concerne également un séparateur de batterie ou une batterie comprenant au moins une membrane ou film microporeux multicouche. La batterie et le séparateur de batterie selon l'invention sont de préférence plus sûrs et plus solides que les batteries et séparateurs de batterie à membranes microporeuses monocouches et tri-couches des antériorités. L'invention concerne également un procédé de fabrication desdits séparateurs, membranes ou films microporeux multicouches.
