Title (EN) ALKALI METAL-SULFUR SECONDARY BATTERY CONTAINING A HYBRID ANODE
(FR) BATTERIE SECONDAIRE MÉTAL ALCALIN-SOUFRE CONTENANT UNE ANODE HYBRIDE
Abstract:
(EN) Provided is an alkali metal-sulfur cell comprises: (A) an anode comprising (i) an anode active material layer composed of fine particles of a first anode active material, an optional conductive additive, and an optional binder and, prior to assembly of the cell, (ii) a layer of an alkali metal or alkali metal alloy having greater than 50% by weight of lithium, sodium, or potassium therein, wherein the layer of alkali metal or alkali metal alloy is in physical contact with the anode active material layer; (B) a cathode active material layer and an optional cathode current collector, wherein the cathode active material layer contains multiple particulates of a sulfur-containing material selected from a sulfur-carbon hybrid, sulfur-graphite hybrid, sulfur-graphene hybrid, conducting polymer-sulfur hybrid, metal sulfide, sulfur compound, or a combination thereof; and (C) an electrolyte in ionic contact with the anode active material layer and the cathode active material layer.
(FR) L'invention concerne un élément métal alcalin-soufre qui comprend : (A) une anode comprenant (i) une couche de matériau anodique actif composée de fines particules d'un premier matériau anodique actif, d'un additif conducteur facultatif et d'un liant facultatif et, avant l'assemblage de l'élément, (ii) une couche d'un métal alcalin ou d'un alliage de métal alcalin contenant plus de 50 % en poids de lithium, de sodium ou de potassium, la couche de métal alcalin ou d'alliage de métal alcalin étant en contact physique avec la couche de matériau anodique actif; (B) une couche de matériau cathodique actif et un collecteur de courant cathodique facultatif, la couche de matériau cathodique actif contenant de multiples particules d'un matériau contenant du soufre choisi parmi un hybride soufre-carbone, un hybride soufre-graphite, un hybride soufre-graphène, un hybride polymère conducteur-soufre, un sulfure métallique, un composé de soufre, ou une combinaison de ceux-ci; et (C) un électrolyte en contact ionique avec la couche de matériau anodique actif et la couche de matériau cathodique actif.
