Patent ID: 7695865

Claim:
A method of manufacturing a solid electrolyte battery having an electric power-generating element composed of a positive electrode, a solid electrolyte layer and a negative electrode that are stacked, the method comprising: thermally pressing a composite layer including a positive electrode particle ink layer, an electrolyte ink layer and a negative electrode particle ink layer that are formed by coating a positive electrode particle ink, an electrolyte ink, and a negative electrode particle ink, wherein the positive electrode particle ink includes a positive electrode polymer particle containing a first polymer electrolyte, the electrolyte ink includes a second polymer electrolyte, and the negative electrode particle ink includes a negative electrode polymer particle containing a third polymer electrolyte, wherein, by thermally pressing the composite layer the first to third polymer electrolytes are integrated and wherein the positive electrode polymer particle and the negative electrode polymer particle have no trace of their original particle forms, thereby eliminating interfaces between the positive electrode particle ink layer and the electrolyte ink layer and between the electrolyte ink layer and the negative electrode particle ink layer.
