Abstract
A solid-state battery in which a decrease in the capacity retention rate is suppressed, and a method for producing the solid-state battery are provided. A solid-state battery comprising an anode layer, a cathode layer and a solid electrolyte layer, wherein the anode layer contains an interface forming agent, and the interface forming agent contains at least one kind of elements selected from metal elements and semi-metal elements, which can become cations which conduct the solid electrolyte contained in the solid electrolyte layer, which are not involved in an electrode reaction, which have lower ionic conductivity than ions involved in the electrode reaction, and which have ionic radii of 1.34 Å or less, and wherein the solid electrolyte layer has dendritic structure in at least one of an interface with the cathode layer and an interface with the anode layer.
