Abstract
An all-solid secondary battery includes an anode layer; a cathode layer; a solid electrolyte layer interposed between the anode layer and the cathode layer, and including a first solid electrolyte; and a first bonding layer disposed between the cathode layer and the solid electrolyte layer, and comprising a second solid electrolyte, wherein the anode layer includes an anode current collector and an anode active material layer disposed on the anode current collector, and the anode active material layer includes a binder and an anode active material, wherein the cathode layer includes a cathode current collector and a cathode active material layer disposed on the cathode current collector, and wherein the second solid electrolyte has a Young's modulus which is less than a Young's modulus of the first solid electrolyte.
