Title
(EN) CATHODES FOR SOLID-STATE LITHIUM SULFUR BATTERIES AND METHODS OF MANUFACTURING THEREOF
(FR) CATHODES POUR BATTERIES AU LITHIUM-SOUFRE À L'ÉTAT SOLIDE ET LEURS PROCÉDÉS DE FABRICATION
Abstract
(EN)
A cathode for a lithium-sulfur battery includes a sulfur-based composite layer having a porosity in a range of 60% to 99%; and a conductive polymer disposed atop the composite layer and within pores of the composite layer. Moreover, a method of forming a cathode for a lithium-sulfur battery includes providing a substrate; disposing a sulfur-based slurry layer on the substrate; freeze-drying the slurry layer to form a sulfur-based composite layer having a porosity in a range of 60% to 99%; and disposing a conductive polymer atop the composite layer and within pores of the composite layer.

Une cathode pour une batterie au lithium-soufre comprend une couche composite à base de soufre ayant une porosité dans une plage de 60 % à 99 % ; et un polymère conducteur disposé au-dessus de la couche composite et à l'intérieur des pores de la couche composite. De plus, un procédé de formation d'une cathode pour une batterie au lithium-soufre comprend l'utilisation d'un substrat ; la disposition d'une couche de bouillie à base de soufre sur le substrat ; la lyophilisation de la couche de bouillie pour former une couche composite à base de soufre ayant une porosité dans une plage de 60 % à 99 % ; et la disposition d'un polymère conducteur au-dessus de la couche composite et à l'intérieur des pores de la couche composite.
