Abstract

An all-solid-state cell has a fired solid electrolyte body, a first electrode layer integrally formed on one surface of the fired solid electrolyte body by mixing and firing an electrode active material and a solid electrolyte, and a second electrode layer integrally formed on the other surface of the fired solid electrolyte body by mixing and firing an electrode active material and a solid electrolyte. The first and the second electrode layers are formed by mixing and firing the electrode active material and the amorphous solid electrolyte, which satisfy the relation Ty>Tz (wherein Ty is a temperature at which the capacity of the electrode active material is lowered by reaction between the electrode active material and the solid electrolyte material, and Tz is a temperature at which the solid electrolyte material is shrunk by firing).

First claim

What is claimed is:

1. An all-solid-state cell comprising:
positive and negative electrode portions containing an electrode active material; and
an electrolyte portion containing a solid electrolyte;
wherein one or both of the positive and negative electrode portions comprises a sintered body of a mixture of the electrode active material and an amorphous solid electrolyte material; and
wherein the electrode active material and the amorphous solid electrolyte material satisfy…
