Methods for recovering materials from solid oxide full-cells and solid oxide cells

A method for recovering a material from a solid oxide full-cell, the method comprising:

• comminuting a solid oxide full-cell comprising one or more of a perovskite electrolyte material and a metal material to produce a powder;
• dissolving the powder in H2SO4 exhibiting a concentration of from about 0.25 Molar (M) H2SO4 to about 1 M H2SO4 to form a leaching solution;
• removing the one or more of the perovskite electrolyte material and the metal material from the leaching solution;
• and
• recovering one or more of the perovskite electrolyte material and the metal material.

A method for recovering a material from a solid oxide cell, the method comprising:

• separating a cathode from a solid oxide half-cell of a solid oxide cell, the solid oxide cell comprising one or more of a perovskite electrolyte material, a metal material, cobalt, praseodymium, and nickel;
• dissolving one or more of the cobalt, praseodymium, and nickel of the cathode into a first leaching solution;
• removing the one or more of cobalt, praseodymium, and nickel from the first leaching solution;
• comminuting the solid oxide half-cell to produce a powder;
• dissolving the powder to form a second leaching solution;
• and
• removing one or more materials from the second leaching solution.
