Patent ID: 11817549

Abstract:
To provide an all-solid-state battery capable of extracting capacitance at lower pressure, despite a binder-less configuration free from an organic polymer compound binder and a method for manufacturing the same.An all-solid-state battery 10 includes a positive electrode layer 11 containing positive electrode active material particles and first solid electrolyte particles, a solid electrolyte layer 13 containing the first solid electrolyte particles, and a negative electrode layer 12 containing negative electrode active material particles and the first solid electrolyte particles, the positive electrode layer 11, the solid electrolyte layer 13, and the negative electrode layer 12 being bonded to one another, in which at least one layer of the positive electrode layer 11, the solid electrolyte layer 13, and the negative electrode layer 12 further contains a second solid electrolyte and the second solid electrolyte has crystallinity and is packed and arranged to fill gaps between the particles.
