1. A method for making a material, the method comprising:
providing a lithium-ion conducting ceramic powder material at a first quantity, the lithium-ion conducting ceramic powder material being characterized by a first density, the lithium-ion conducting ceramic powder material being characterized by a median particle size of about 100 nm to 10 μm; providing a first flux material at a second quantity, the second quantity being less than 51% of the first quantity, the first flux material comprising lithium-ion ceramic powder material, the first flux material being characterized by a melting temperature of about 500-1000° C.; providing a second flux material at a third quantity, the second flux material being characterized by a melting temperature of about 500-1000° C.; mixing at least the first flux material and the second flux material to form a eutectic mixture, the eutectic mixture being characterized by a melting point of less than 800° C.; subjecting the eutectic mixture to a temperature of about 100 to 1100° C.; mixing the eutectic mixture with the lithium-ion conducting ceramic powder material to form a fluxed ceramic powder material; shaping the fluxed ceramic powder material into a predetermine shape; heating the shaped fluxed ceramic powder material to a temperature of less than 1100° C.; and forming a dense lithium-ion conducting material, the dense lithium-ion conducting material being characterized by a second density, the second density is at least 20% higher than the first density; wherein the lithium-ion conducting ceramic powder material comprises electrolyte component powders selected from one or more of metal oxides, nitrates, carbonates, sulfates, borates, or hydroxides; and wherein the electrolyte component powders is characterized by a quantity less than the second quantity. |
