  • Garnet-lithium titanate composite electrolyte
    Patent number: 11858854
    Abstract: A sintered composite ceramic includes: a lithium-garnet major phase; and a lithium-rich minor phase, such that the lithium-rich minor phase has LixTiO(x+4)/2, with 0.66?x?4. The sintered composite ceramic may exhibit a relative density of at least 90% of a theoretical maximum density of the ceramic, an ionic conductivity of at least 0.35 mS·cm?1, or a critical current density (CCD) of at least 1.0 mA·cm?2.
    Type: Grant

  • LI-METAL OXIDE/GARNET COMPOSITE THIN MEMBRANE AND METHOD OF MAKING
    Publication number: 20230118975
    Abstract: A sintered composite ceramic includes a lithium-garnet major phase; and a lithium dendrite growth inhibitor minor phase, such that the lithium dendrite growth inhibitor minor phase comprises lithium tungstate. A method includes sintering a metal oxide component and a garnet component at a temperature in a range of 750° C. to 1500° C. to form a sintered composite ceramic.
