1. A Faradaic solid-state energy storage device comprising:

  • a first electrode,wherein the first electrode has a first thickness greater than 1 nm and less than or equal to 80 nm, andwherein the first electrode comprises a first redox-supporting metal, an oxide of the first redox-supporting metal, or a combination of the first redox-supporting metal and the oxide of the first redox-supporting metal;

    a solid electrolyte positioned in direct contact with the first electrode,wherein the solid electrolyte has a second thickness greater than 1 nm and less than or equal to 500 nm, andwherein the solid electrolyte comprises a solid-state, oxygen ion conducting ceramic electrolyte, wherein the solid-state, oxygen ion conducting ceramic electrolyte has a crystal structure including vacancies that permit conduction or migration of oxygen ions through the crystal structure; and

    a second electrode positioned in direct contact with the solid electrolyte,wherein the second electrode has a third thickness greater than 1 nm and less than or equal to 80 nm, andwherein the second electrode comprises a second redox-supporting metal, an oxide of the second redox-supporting metal, or a combination of the second redox-supporting metal and the oxide of the second redox-supporting metal.
