Abstract
Official abstract text for this publication.
Provided is an all-solid-state battery with high charge-discharge efficiency. Disclosed is an all-solid-state battery, wherein the all-solid-state battery comprises a cathode comprising a cathode layer, an anode comprising an anode layer, and a solid electrolyte layer disposed between the cathode layer and the anode layer; wherein the anode layer contains at least one selected from the group consisting of a lithium metal and a lithium alloy; and wherein a protective layer comprising a composite metal oxide represented by Li-M-O (where M is at least one metal element selected from the group consisting of Mg, Au, Al and Sn) is disposed between the anode layer and the solid electrolyte layer.
First claim
Opening claim text (preview).
