Abstract
An oxide all-solid-state battery excellent in lithium ion conductivity and joint strength between an anode active material layer and solid electrolyte layer thereof. In the oxide all-solid-state battery, the solid electrolyte layer is a layer mainly containing a garnet-type oxide solid electrolyte sintered body represented by the following formula (1): (Li, E, H)LMO; a solid electrolyte interface layer is disposed between the anode active material layer and the solid electrolyte layer; the solid electrolyte interface layer contains at least a Si element and an O element; and a laminate containing at least the anode active material layer, the solid electrolyte interface layer and the solid electrolyte layer has peaks at positions where 2θ=32.3°±0.5°, 37.6°±0.5°, 43.8°±0.5°, and 57.7°±0.5° in a XRD spectrum obtained by XRD measurement using CuKα irradiation.
