Abstract
A method for producing an electrode comprising a porous garnet-type ion-conducting oxide sintered body with high ion conductivity, the electrode, and an electrode-electrolyte layer assembly comprising the electrode and an electrolyte layer comprising a dense garnet-type ion-conducting oxide sintered body with high ion conductivity. Disclosed is a method for producing an electrode, the method comprising: preparing crystal particles of a garnet-type ion-conducting oxide; preparing a lithium-containing flux; preparing the electrode active material; preparing an electrolyte material by mixing the crystal particles of the garnet-type ion-conducting oxide and the flux; and sintering the electrolyte material and the electrode active material by heating at a temperature of 650° C. or less, wherein a number average particle diameter of the flux is larger than a number average particle diameter of the crystal particles of the garnet-type ion-conducting oxide.
