    Abstract: An all-solid-state battery includes: a positive electrode layer including a positive electrode current collector and a positive electrode mixture layer; a negative electrode layer including a negative electrode current collector and a negative electrode mixture layer; and a solid electrolyte layer. The solid electrolyte layer is disposed between the positive electrode mixture layer and the negative electrode mixture layer. A weight per unit area of a first portion of the negative electrode mixture layer overlapping the positive electrode mixture layer on a stacking axis is greater than a weight per unit area of a second portion of the negative electrode mixture layer not overlapping the positive electrode mixture layer on the stacking axis.

    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.

    Abstract: An electrode includes a collector, and an active material mixture layer located on the collector and containing first particles, second particles, first active material particles, and second active material particles. The active material mixture layer includes a first mixture layer located on the collector and containing the first particles and the first active material particles, and a second mixture layer located on the first mixture layer and containing the second particles and the second active material particles. The active material mixture layer has a boundary in which the first active material particles and the second active material particles are in contact with each other in a discontinuous state at least in part, in a cross-sectional view of the electrode.

    Abstract: An all-solid-state battery includes: a positive electrode layer including a positive electrode current collector and a positive electrode mixture layer; a negative electrode layer including a negative electrode current collector and a negative electrode mixture layer; and a solid electrolyte layer. The solid electrolyte layer is disposed between the positive electrode mixture layer and the negative electrode mixture layer. On a plane perpendicular to a stacking axis, an area of the negative electrode mixture layer is larger than an area of the positive electrode mixture layer. On the stacking axis, an entire portion of the positive electrode mixture layer overlaps a portion of the negative electrode mixture layer.
