Patent ID: 11444319

Abstract:
An all-solid battery includes a positive-electrode layer, a negative-electrode layer, and a solid electrolyte layer. The positive-electrode layer includes a positive-electrode current collector, a positive-electrode bonding layer containing at least a conductive agent comprising non-metal and formed on the positive-electrode current collector, and a positive-electrode mixture layer containing at least a positive-electrode active material and a solid electrolyte and formed on the positive-electrode bonding layer. The negative-electrode layer includes a negative-electrode current collector and a negative-electrode mixture layer containing at least a negative-electrode active material and the solid electrolyte. The solid electrolyte layer is disposed between the positive-electrode mixture layer and the negative-electrode mixture layer and contains the solid electrolyte. A concentration of a binder contained in the positive-electrode mixture layer is less than or equal to 100 ppm and a concentration of a solvent contained in the positive-electrode mixture layer is less than or equal to 50 ppm.
