1. A method for forming a metal oxide electrolyte, comprising:
applying a metal compound to a first material in powder form thereby forming a slurry;
applying the slurry to an electrode; and
converting at least some of the metal compound to form a metal oxide, thereby forming the metal oxide electrolyte on the electrode;
wherein the metal oxide electrolyte has an ionic conductivity greater than the bulk ionic conductivity of the first material and of the metal oxide.
