SOLID-STATE BATTERY

Abstract:

To provide a solid-state battery that can improve layout by allowing a current collecting position to be optionally disposed and that can suppress the occurrence of short circuits. A solid-state battery includes a positive electrode, a negative electrode, and a solid electrolyte layer disposed between the positive electrode and the negative electrode. A first electrode selected from one of the positive electrode and the negative electrode includes a material mixture filled portion including a metal porous body filled with an electrode material mixture. The solid electrolyte layer is disposed so as to cover a periphery of the material mixture filled portion. A second electrode selected from the other of the positive electrode and the negative electrode is disposed so as to cover the solid electrolyte layer.
