Abstract: Provided herein is a solid-state battery having high volume energy density, as well as a method of manufacture of such a solid-state battery. A solid-state battery 100 is a laminate including a first collector layer 1, a positive electrode layer 2, a solid electrolyte layer 5, a negative electrode layer 4, and a second collector layer 3, in this order from the top. The solid-state battery 100 satisfies α>90°, β>90°, and α>β, where α is the angle formed in the positive electrode layer 2 by a side surface 2A of the positive electrode layer 2 and the top surface of the solid electrolyte layer 5 underlying the positive electrode layer 2, and β is the angle formed in the negative electrode layer 4 by a side surface 4A of the negative electrode layer 4 and the top surface of the second collector layer 3 underlying the negative electrode layer 4.

Abstract: An all-solid battery is formed by laminating a first current collector, a positive-electrode layer, a solid electrolyte layer, a negative-electrode layer, and a second current collector in this order. The positive-electrode fine particle layer contains positive-electrode active material fine particles having a particle diameter smaller than that of the positive-electrode active material and is formed on a side surface of the positive-electrode layer. The negative-electrode fine particle layer contains negative-electrode active material fine particles having a particle diameter smaller than that of the negative-electrode active material and is formed on a side surface of the negative-electrode layer.
