Abstract
Official abstract text for this publication.
Provided is a laminate that is configured to suppress a deterioration in the all-solid-state battery even if the end part of the anode layer is cracked. The laminate may be a laminate comprising an anode layer, a solid electrolyte layer and a cathode layer in this order, wherein an area in a planar direction of the cathode layer is smaller than an area in a planar direction of the anode layer; wherein an end part of the cathode layer comprises, on the solid electrolyte layer, a thin film part having a smaller thickness than a thickness of a central part of the cathode layer; and wherein the end part of the cathode layer comprises, on the thin film part, a space part formed by a level difference between the thin film part and the central part.
First claim
Opening claim text (preview).
The invention claimed is: 1. A laminate comprising an anode layer, a solid electrolyte layer and a cathode layer in this order, wherein an area in a planar direction of the cathode layer is smaller than an area in a planar direction of the anode layer; wherein an end part of the cathode layer comprises, on the solid electrolyte layer, a thin film part having a smaller thickness than a thickness of a central part of the cathode layer; wherein the end part of the cathode layer comprises, on the thin film part, a space part formed by a level difference between the thin film part and the central part; where the thin film part of the cathode layer contacts the solid electrolyte layer, and the space part is formed between the thin film part and a cathode current collector wherein an electroconductive material is contained in the space part of the cathode layer; and wherein the end part of the cathode layer is an edge of the cathode layer in a planar direction of the laminate. 2. The laminate according to claim 1 , wherein an adhesive is contained in the space part of the cathode layer. 3. The laminate according to claim 2 , wherein the adhesive comprises an electroconductive substance which contains at least one kind of powder selected from the group consisting of carbon powder and aluminum powder. 4. The laminate according to claim 1 , wherein the electroconductive material and optionally an adhesive substantially fills the space part.
