  • LITHIUM, PHOSPHORUS, SULFUR, AND IODINE CONTAINING ELECTROLYTE AND CATHOLYTE COMPOSITIONS, ELECTROLYTE MEMBRANES FOR ELECTROCHEMICAL DEVICES, AND ANNEALING METHODS OF MAKING THESE ELECTROLYTES AND CATHOLYTES
    Publication number: 20230123228
    Abstract: The present disclosure sets forth battery components for secondary and/or traction batteries. Described herein are new solid-state lithium (Li) conducting electrolytes including monolithic, single layer, and bi-layer solid-state sulfide-based lithium ion (Li+) conducting catholytes or electrolytes. These solid-state ion conductors have particular chemical compositions which are arranged and/or bonded through both crystalline and amorphous bonds. Also provided herein are methods of making these solid-state sulfide-based lithium ion conductors including new annealing methods. These ion conductors are useful, for example, as membrane separators in rechargeable batteries.
