Title
(EN) PRINTING NANOPOROUS ULTRATHIN MEMBRANES FOR LITHIUM-SULFUR BATTERIES
(FR) IMPRESSION DE MEMBRANES ULTRAMINCES NANOPOREUSES POUR DES PILES AU LITHIUM-SOUFRE
Abstract
(EN)
A method of making a composite membrane for a lithium-sulfur (Li-S) battery is described. The method includes providing a polymeric separator membrane; synthesizing a graphene oxide (GO) dispersion; and printing the GO dispersion onto at least one surface of the polymeric separator membrane. The GO coating includes a GO layer.
(FR)
L'invention concerne un procédé de fabrication d'une membrane composite pour des piles au lithium-soufre (Li-S). Le procédé comprend l'utilisation d'une membrane séparatrice polymère; la synthèse d'une dispersion d'oxyde de graphène (OG); l'impression de la dispersion d'OG sur au moins une surface de la membrane séparatrice polymère. Le revêtement d'OG comprend une couche d'OG.
