摘要： A metal-air battery including an anode layer; a solid electrolyte layer; and a cathode layer directly contacting the solid electrolyte layer. The solid electrolyte layer and the cathode layer are a single unitary and indivisible body with no physical interlayer boundary between the solid electrolyte layer and the cathode layer. A portion of the cathode layer may be within the solid electrolyte layer. The cathode layer may protrude from the solid electrolyte layer. The method of manufacturing a metal-air battery may include forming a solid electrolyte layer on an anode layer and chemically reducing solid electrolyte in a part of the solid electrolyte layer.
