Abstract: An all-solid-state battery includes a positive-electrode current collector, a positive electrode layer, a negative-electrode current collector, a negative electrode layer, and a solid electrolyte layer. The positive electrode layer is formed on the positive-electrode current collector and includes a positive-electrode material mixture layer which includes at least a positive-electrode active material and a binder. The negative electrode layer is formed on the negative-electrode current collector and includes a negative-electrode material mixture layer which includes at least a negative-electrode active material and a binder. The solid electrolyte layer is disposed between the positive-electrode material mixture layer and the negative-electrode material mixture layer, and includes at least a solid electrolyte having ion conductivity.

Abstract: Provided is a stacked all-solid-state battery including a plurality of all-solid-state batteries, each all-solid-state battery including a cathode layer that has a cathode current collector and a cathode active material layer containing a cathode active material and formed on the cathode current collector, an anode layer that has an anode current collector and an anode active material layer containing an anode active material and formed on the anode current collector, and a solid electrolyte layer disposed between the cathode active material layer and the anode active material layer and containing a solid electrolyte having a lithium ion conductivity. The plurality of all-solid-state batteries are stacked, and the plurality of all-solid-state batteries include two adjacent all-solid-state batteries, the two all-solid-state batteries being configured such that the cathode current collector of one all-solid-state battery is directly joined to the anode current collector of the other all-solid-state battery.
