Japanese Patent JP7042058

Kind Code:

B2

Abstract:

To provide an all-solid battery in which the mutual diffusion of a solid electrolyte layer and a margin layer during burning can be suppressed, and an unexpected battery reaction through the margin layer can be suppressed.SOLUTION: An all-solid battery comprises: a solid electrolyte layer; a positive electrode layer formed on one face of the solid electrolyte layer, part of which reaches a first edge of the solid electrolyte layer; a first margin layer formed on a part of the one face of the solid electrolyte layer, where the positive electrode layer is not provided; a negative electrode layer formed on the other face of the solid electrolyte layer, part of which reaches a second edge different from the first edge of the solid electrolyte layer; and a second margin layer formed on a part of the other face of the solid electrolyte layer, where the negative electrode layer is not provided. The first and second margin layers include a solid electrolyte lower in ion conductivity than the solid electrolyte layer as a primary component.SELECTED DRAWING: Figure 1
