  • Lithium-stuffed garnet thin films and pellets having an oxyfluorinated and/or fluorinated surface and methods of making and using the thin films and pellets
    Patent number: 11817551
    Abstract: Set forth herein are processes for making lithium-stuffed garnet oxides (e.g., Li7La3Zr2O12, also known as LLZO) that have passivated surfaces comprising a fluorinate and/or an oxyfluorinate species. These surfaces resist the formation of oxides, carbonates, hydroxides, peroxides, and organics that spontaneously form on LLZO surfaces under ambient conditions. Also set forth herein are new materials made by these processes.

    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.
