Abstract

Official abstract text for this publication.

There is provided a solid-state battery which can prevent short circuiting or breakage from occurring in electrode layers in individual laminates due to rolling when the stacked laminates are subjected to a high-pressure pressing process. A solid-state battery includes a laminate in which a positive electrode collector, a positive electrode active material layer, a solid electrolyte layer, a negative electrode active material layer, and a negative electrode collector are stacked in this order, and a conductive rigid body including a rigid body having electrical conductivity, wherein the laminate and the conductive rigid body are alternately stacked, and the conductive rigid body is provided on each outermost side in a stacking direction.

First claim

Opening claim text (preview).

What is claimed is: 1 . A solid-state battery comprising: a laminate in which a positive electrode collector, a positive electrode active material layer, a solid electrolyte layer, a negative electrode active material layer, and a negative electrode collector are stacked in this order; and a conductive rigid body including a rigid body having electrical conductivity, wherein the laminate and the conductive rigid body are alternately stacked, and the conductive rigid body is provided on each outermost side in a stacking direction. 2 . A solid-state battery comprising: an assembly in which a pair of laminates each in which a positive electrode collector, a positive electrode active material layer, a solid electrolyte layer, a negative electrode active material layer, and a negative electrode collector are stacked in this order are stacked so that the positive electrode collectors of the pair of laminates contact each other; and a conductive rigid body including a rigid body having electrical conductivity, wherein the assembly and the conductive rigid body are alternately stacked and the conductive rigid body is provided on each outermost side in a stacking direction. 3 . The solid-state battery according to claim 1 , wherein edges in a planar direction of the positive electrode active material layer are provided on an inner side in the planar direction with respect to edges in the planar direction of the solid electrolyte layer that is adjacent to the positive electrode active material layer. 4 . The solid-state battery of claim 1 , further comprising: an insulating spacer provided outside in a planar direction of the positive electrode active material layer.
