Claim 16:
17. A sintered composite ceramic, comprising:
a lithium-garnet major phase; and
a lithium-rich minor phase, the lithium-rich minor phase comprises LixTiO(x+4)/2, with 0.66≤x≤4
wherein a mass ratio of lithium-garnet major phase to lithium-rich minor phase is in a range of 100:2 to 100:8, and
wherein the ceramic comprises at least one of:
(i) a relative density of at least 90% of a theoretical maximum density of the ceramic,
(ii) an ionic conductivity of at least 0.35 mS·cm−1, and
(iii) a critical current density (CCD) of at least 1.0 mA·cm−2.
