摘要： Herein discussed is a method of making a copper-containing electrode comprising: (a) forming a copper solution; (b) forming a ceramic substrate; (c) infiltrating the ceramic substrate with the copper solution; and (d) calcining the infiltrated substrate using electromagnetic radiation, wherein the substrate is no thicker than 50 microns. In an embodiment, the method comprises repeating (c) and (d) until copper percolates the ceramic substrate.

摘要： Herein discussed is a method of making an electrochemical device comprising (a) infiltrating an anode precursor, a cathode precursor, and an electrolyte precursor with a dispersion to produce an infiltrated anode precursor, an infiltrated cathode precursor, and an infiltrated electrolyte precursor, wherein the dispersion comprises metal ions and nanoparticles selected from the group consisting of metallic nanoparticles, metal-oxide nanoparticles, ceramic nanoparticles, and combinations thereof; wherein the metal ions percolate each precursor, wherein the anode precursor, the cathode precursor, and the electrolyte precursor are porous, the electrolyte precursor having an average pore size that is 50% or less of an average pore size of the anode precursor and that is 50% or less of an average pore size of the cathode precursor; and (b) co-sintering the infiltrated anode precursor, the infiltrated cathode precursor, and the infiltrated electrolyte precursor such that the infiltrated anode precursor becomes a porous anode, the infiltrated cathode precursor becomes a porous cathode, and a gas tight electrolyte is formed between the porous anode and the porous cathode.
