Abstract
Official abstract text for this publication.
Provided is an electrode laminate for all-solid-state batteries, which is configured to suppress the occurrence of short circuits in all-solid-state batteries and/or to suppress a decrease in the durability of all-solid-state batteries, and which is configured to suppress an increase in the resistance value of all-solid-state batteries. Disclosed is an electrode laminate for all-solid-state batteries, comprising: a current collector complex comprising adhesive portions and a current collector portion that comprises at least a current collector, and an active material layer disposed on the current collector complex, wherein an active material layer-side main surface of the current collector portion and active material layer-side main surfaces of the adhesive portions are formed to be one flat surface, and the current collector portion and the active material layer are attached by the adhesive portions.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electrode laminate for all-solid-state batteries, comprising: a current collector complex comprising adhesive portions and a current collector portion that comprises at least a current collector and a carbon coat layer formed with one or more holes, wherein the carbon coat layer is formed directly on the current collector, and an active material layer disposed on the current collector complex, wherein an active material layer-side main surface of the current collector portion and active material layer-side main surfaces of the adhesive portions are formed in the holes to form a coplanar surface, and the current collector portion and the active material layer are attached by the adhesive portions. 2. A method for producing an electrode laminate for all-solid-state batteries, the method comprising: forming a current collector complex comprising adhesive portions and a current collector portion that comprises at least a current collector and a carbon coat layer formed with one or more holes, wherein the carbon coat layer is formed directly on the current collector, main surfaces of the adhesive portions are formed in the one or more holes of the carbon coat layer to form a coplanar surface, and attaching the current collector portion and an active material layer by the adhesive portions by forming the active material layer on a main surface of the current collector complex, which is a main surface on a side where the adhesive portions are exposed. 3. The electrode laminate for all-solid-state batteries according to claim 1 , wherein the adhesive portions are disposed at the four corners of the carbon coat layer. 4. The electrode laminate for all-solid-state batteries according to claim 1 , wherein the adhesive portion is disposed at the center of the carbon coat layer. 5. The method for producing the electrode laminate for all-solid-state batteries according to claim 2 , wherein the adhesive portions are disposed at the four corners of the carbon coat layer. 6. The method for producing the electrode laminate for all-solid-state batteries according to claim 2 , wherein the adhesive portion is disposed at the center of the carbon coat layer.
