ALL-SOLID-STATE CELL

摘要

An all-solid-state cell contains a combination of an electrode active material and a solid electrolyte, and has a plate-shaped fired solid electrolyte body of a ceramic containing a solid electrolyte, a first electrode layer (e.g. a positive electrode) 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 (e.g. a negative electrode) 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 solid electrolyte materials added to the first electrode layer and the second electrode layer comprise an amorphous polyanion compound.

主权项

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 the all-solid-state cell is free of liquid and is entirely composed of ceramic materials; wherein the electrode active material and the solid electrolyte contain the same polyanion; and wherein one or both of the positive and negative electrode portions comprise a sintered body of a mixture of the electrode active material and an amorphous solid electrolyte containing an amorphous polyanion compound.
