摘要： A cerium-zirconium oxide-based ionic conductor (CZOIC) material including zirconium oxide in an amount ranging from 5 wt. % up to 95 wt. %, cerium oxide in an amount ranging from 95 wt. % to 5 wt. %, and at least one oxide or a rare earth metal in an amount ranging from 30 wt. % or less, based on the overall mass of the CZOIC material. The CZOIC material exhibits a structure comprising one or more expanded unit cells and a plurality of crystallites having ordered nano-domains. The structure of the CZOIC material exhibits a crystal lattice defined by a d-value measured at multiple (hkl) locations using a SAED technique that exhibit distortions, such that the d-values for the same (hkl) location varies from about 2% to about 5% from the d-value measured for a reference cerium-zirconium material at the same (hkl) location.

摘要： 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.

摘要： The present invention relates to a method of preparation of a garnet-type inorganic material. It also relates to the garnet-type inorganic material itself. The process comprises the following steps: (1) bringing an aqueous solution S comprising (i) a salt of zirconium, (ii) a salt of lanthanum and (iii) a salt of the element A or a precursor of an oxide of element A into contact with an aqueous solution of a basic compound, as a result of which a precipitate suspended in the reaction medium is obtained; (2) stirring the reaction medium obtained at the end of step (1) for at least 30 min; (3) bringing the precipitate obtained at the end of step (2) into contact with an additive selected in the group consisting of: anionic surfactants; nonionic surfactants; polyethylene glycols; carboxylic acids and their salts; and surfactants of the carboxymethylated fatty alcohol ethoxylate type; (4) calcining in air the precipitate recovered at the end of the previous step at a temperature which is at least 400° C.; (5) bringing into contact the product obtained at the end of step (4) with a salt of lithium; (6) calcining in air the product obtained at the end of step (5) at a temperature between 700° C. and 1100° C.; 20 the inorganic compound M comprising or consisting essentially of a garnet oxide or garnet-type oxide containing, as constituent elements, the elements Li, La, Zr and at least one element A selected in the group consisting of Al, Ga, Nb, Fe, W, Ta, or a mixture thereof.
