ALL-SOLID-STATE BATTERY AND METHOD OF MANUFACTURING THE SAME

An all-solid-state battery and a method of manufacturing the same. The all-solid-state battery includes a multilayer structure, a first cover layer and a second cover layer opposite the first cover layer. The multilayer structure includes a solid electrolyte layer including a solid electrolyte, a cathode layer provided on a first side of the solid electrolyte layer, a portion of which extends to a first edge of the solid electrolyte layer, a first margin layer provided on an area of the first side of the solid electrolyte layer, an anode layer provided on a second side of the solid electrolyte layer, and a second margin layer provided on an area of the second side of the solid electrolyte layer. Moreover, at least one of the first cover layer, the second cover layer, the first margin layer, or the second margin layer includes an oxide including a pyrochlore crystalline material.
