Abstract
Official abstract text for this publication.
A solid-state battery includes: a first current collector that includes a first metal layer and a first resin layer containing a resin and a conductive material; a first active material layer; a solid-state electrolyte layer; a second active material layer, and a second current collector that includes a second metal layer and a second resin layer containing a resin and a conductive material, which are layered in this order, wherein the first current collector is provided with the first resin layer at a first active material layer side, and the second current collector is provided with the second resin layer at a second active material layer side.
First claim
Opening claim text (preview).
What is claimed is: 1 . A solid-state battery, comprising: a first current collector that includes a first metal layer and a first resin layer containing a resin and a conductive material; a first active material layer; a solid-state electrolyte layer; a second active material layer, and a second current collector that includes a second metal layer and a second resin layer containing a resin and a conductive material, which are layered in this order, wherein the first current collector is provided with the first resin layer at a first active material layer side, and the second current collector is provided with the second resin layer at a second active material layer side. 2 . The solid-state battery according to claim 1 , further comprising: between the first current collector and the first active material layer, a first intermediate layer in which at least one component contained in the first active material layer and at least one component contained in the first resin layer are present in a mixed state; and between the second current collector and the second active material layer, a second intermediate layer in which at least one component contained in the second active material layer and at least one component contained in the second resin layer are present in a mixed state. 3 . The solid-state battery according to claim 1 , wherein: the first resin layer includes a resin layer A and a resin layer B, the second resin layer includes a resin layer C and a resin layer D, the first current collector has a three-layer structure in which the resin layer A, the first metal layer, and the resin layer B are layered in this order from the first active material layer side; and the second current collector has a three-layer structure in which the resin layer C, the second metal layer, and the resin layer D are layered in this order from the second active material layer side. 4 . The solid-state battery according to claim 2 , wherein: the first resin layer includes a resin layer A and a resin layer B, the second resin layer includes a resin layer C and a resin layer D, the first current collector has a three-layer structure in which the resin layer A, the first metal layer, and the resin layer B are layered in this order from the first active material layer side; and the second current collector has a three-layer structure in which the resin layer C, the second metal layer, and the resin layer D are layered in this order from the second active material layer side.
