Abstract
An all-solid-state battery includes a pair of electrode layers consisting of first and second electrode layers, and a solid-state electrolyte layer positioned between the pair of electrode layers, wherein the first electrode layer contains an electrode active material having an olivine-type crystalline structure, the solid-state electrolyte layer contains a solid-state electrolyte having a NASICON-type crystalline structure, and the solid-state electrolyte layer in the vicinity of the first electrode layer is expressed by a composition formula LixAyCozM′aM″bP3Oc. The all-solid-state battery can improve the long-term cycle stability.
