TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Device: The energy storage device comprises battery, fuel cell, or semi-fuel cell; and at least one electrode which include hydrogen, lithium, sodium, magnesium, aluminum or gallium.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: In the method (M1), the chelating agent, a first non-aqueous organic solvent and a first metallic compound are combined to form a first metal cation solution, where second and third metallic compounds and a second non-aqueous organic solvent are combined to form a second metal cation solution, and the first and second metal cation solutions are combined to produce the oxide ceramic solid. The method (M1) further involves combining an aluminum compound and/or an aqueous solution with the first, second and/or third metal cation solutions and/or the oxide ceramic gel. The method (M1) further involves: optionally drying the oxide ceramic solid to produce a dried oxide ceramic solid; heating the dried oxide ceramic solid to produce a crystalline or partially crystalline oxide ceramic powder; optionally milling the crystalline or partially crystalline oxide ceramic powder to produce reduced-size crystalline or partially crystalline oxide ceramic powder; and densifying the reduced-size crystalline or partially crystalline oxide ceramic powder to produce a densified oxide ceramic solid, where the densifying can comprise heating, and/or pressing. The method (M1) further involves heat-treating the milled oxide ceramic powder and/or the pressed oxide ceramic pellet. In the method (M2), the step of forming includes ink-jet printing the slurry on the oxide ceramic electrolyte, self-assembled patterning, using a mold, stamping the 3D feature into the slurry or using a mold; the mold comprises fibers bonded to the oxide ceramic electrolyte or a patterned sheet; and the 3D features on the oxide ceramic electrolyte are arranged in a pattern to form an electrolyte interface with hierarchical and highly ordered porosity. Preferred Components: The non-aqueous solution-based reaction comprises a gelation portion and a condensation portion, and the method further involves adding supervalent cation during the gelation portion of the non-aqueous solution-based reaction. The oxide ceramic solid is a cubic garnet having atomic formula A'xRyC'zSaO12. The cubic garnet has a nominal formula of Li7La3Zr2O12. The densified oxide ceramic solid is a pressed oxide ceramic pellet.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The first and second non-aqueous organic solvents are selected from methanol, ethanol, n-propanol, isopropanol, n-butanol, tert-butanol, chloroform, and/or N,N-dimethylformamide. The chelating agent is selected from an organic acid, mineral acid, and/or an amine. EXAMPLE - A 0.172 ml acetic acid was added to 5.258 ml n-propanol and stirred for 5 minutes. A 0.896 ml zirconium n-propoxide was added to the solution and stirred for 20 minutes. A 1.36 mg aluminum oxide powder was added to the solution and stirred for 10 minutes to produce a zirconium/aluminum oxide solution. A 1.299 g lanthanum nitrate hexahydrate was added to 5.258 ml n-propanol and stirred for 10 minutes. A 0.487 g lithium nitrate hydrate was added to the solution and stirred for 30 minutes to produce a lithium-lanthanum solution. The lithium-lanthanum solution was added dropwise to the zirconium solution to produce n-propanol lithium-lanthanum-zirconate gel.
