Abstract
Official abstract text for this publication.
A method of manufacturing an electrode laminate, which includes an active material layer and a solid electrolyte layer formed on the active material layer, includes: an active material layer forming step of forming an active material layer; and a solid electrolyte layer forming step of forming a solid electrolyte layer on the active material layer by applying a solid electrolyte layer-forming slurry to the active material layer and drying the solid electrolyte layer-forming slurry. In this method, a product of a filling factor of the active material layer and a volume proportion of an active material in the active material layer is 0.33 to 0.41.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of manufacturing an electrode laminate which includes an active material layer and a solid electrolyte layer formed on the active material layer, the method comprising: forming the active material layer; and forming the solid electrolyte layer on the active material layer by applying a solid electrolyte layer-forming slurry to the active material layer and drying the solid electrolyte layer-forming slurry, wherein a product of a filling factor of the active material layer and a volume proportion of an active material in the active material layer is 0.33 to 0.41. 2 . The method according to claim 1 , wherein the active material layer is pressed. 3 . A method of manufacturing an all-solid-state battery which includes a positive electrode current collector layer, a positive electrode active material layer, a solid electrolyte layer, a negative electrode active material layer, and a negative electrode current collector layer in this order, the method comprising: forming the positive electrode active material layer and the negative electrode active material layer on the positive electrode current collector layer and the negative electrode current collector layer, respectively; forming the solid electrolyte layer on at least one of the positive electrode active material layer or the negative electrode active material layer by applying a solid electrolyte layer-forming slurry to the at least one of the positive electrode active material layer or the negative electrode active material layer and drying the solid electrolyte layer-forming slurry; and laminating the positive electrode current collector layer, the positive electrode active material layer, the solid electrolyte layer, the negative electrode active material layer, and the negative electrode current collector layer in this order and joining the positive electrode current collector layer, the positive electrode active material layer, the solid electrolyte layer, the negative electrode active material layer, and the negative electrode current collector layer to each other such that the solid electrolyte layer is interposed between the positive electrode active material layer and the negative electrode active material layer, wherein a product of a filling factor of the positive electrode active material layer and the negative electrode active material layer and a volume proportion of an active material in the positive electrode active material layer and the negative electrode active material layer, respectively, is 0.33 to 0.41.
