Abstract
Disclosed is an air electrode for a metal-air battery, the air electrode including a separator composed of a hydroxide-ion-conductive inorganic solid electrolyte being a dense ceramic material, and an air electrode layer disposed on the separator and containing an air electrode catalyst, an electron-conductive material, and a hydroxide-ion-conductive material, or containing an air electrode catalyst also serving as an electron-conductive material and a hydroxide-ion-conductive material. According to the present invention, the reaction resistance of the air electrode including the dense ceramic separator can be significantly reduced in a metal-air battery while ensuring the desired characteristics of the dense ceramic separator.
