1. A solid-state sodium-carbon dioxide battery, which comprises a positive electrode, a negative electrode, an inorganic solid-state electrolyte disposed between the positive electrode and the negative electrode, and at least one of a positive electrode interface layer and a negative electrode interface layer, wherein the positive electrode can catalyze the reaction of sodium ions and carbon dioxide, the positive electrode interface layer is disposed between the positive electrode and the inorganic solid-state electrolyte, and the negative electrode interface layer is disposed between the negative electrode and the inorganic solid-state electrolyte,
wherein the negative electrode comprises sodium and a non-sodium material selected from the group consisting of soft carbon, hard carbon, carbon nanotubes, carbon fiber, coal, asphalt, carbon nitride, carbon quantum dots, and combinations thereof,
wherein the inorganic solid-state electrolyte is selected from the group consisting of Na3Zr2Si2PO12, Na11Sn2PS12, and combinations thereof, and
wherein the materials of the positive electrode interface layer and the negative electrode interface layer are each independently selected from the group consisting of succinonitrile, polyacrylonitrile, polypropylene, polypropylene carbonate, hexafluoropropylene copolymer, sodium perchlorate, sodium hexafluorophosphate, sodium bis(trifluoromethanesulfonyl)imide, sodium bis(fluorosulfonyl)imide, reaction products obtained by co-heating sodium and Na3Zr2Si2PO12, and combinations thereof.
