Abstract

Official abstract text for this publication.

A method is provided for preparing an all-solid battery that at least includes a negative electrode layer containing a negative electrode active material and a sulfide solid electrolyte, and a negative electrode current collector containing a metal that is in contact with the negative electrode layer and can react with the sulfide solid electrolyte, in which a sulfur compound generated by a reaction of the metal contained in the negative electrode current collector and the sulfide solid electrolyte contained in the negative electrode layer is not present in a contact portion of the negative electrode layer and the negative electrode current collector.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for manufacturing an all-solid battery provided with at least a negative electrode layer containing a negative electrode active material and a sulfide solid electrolyte, and a negative electrode current collector containing one, two or more elements selected from the group of Cu, Fe, Ni, Co, and Ti that is in contact with the negative electrode layer comprising: preparing a mock all-solid battery provided with the negative electrode layer, a positive electrode layer, a solid electrolyte layer disposed between the negative electrode layer and the positive electrode layer, a mock current collector connected to the negative electrode layer using the mock current collector that does not react with the sulfide solid electrolyte contained in the negative electrode layer and has electric conductivity; charging the mock all-solid battery; and replacing the mock current collector with the negative electrode current collector after the mock all-solid battery was charged. 2. The method for manufacturing an all-solid battery according to claim 1 , wherein the element contained in the negative electrode current collector is Cu and a contact portion of the negative electrode layer with the negative electrode current collector does not exceed 100° C. after the negative electrode current collector was brought into contact with the negative electrode layer. 3. The method for manufacturing an all-solid battery according to claim 1 , wherein the element contained in the negative electrode current collector is Fe, and a contact portion of the negative electrode layer with the negative electrode current collector does not exceed 125° C. after the negative electrode current collector was brought into contact with the negative electrode layer.
