ALL SOLID SECONDARY BATTERY, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a high-power all solid secondary battery; and its simple manufacturing method.

SOLUTION: This manufacturing method is characterized by applying electricity to (charging) a layered product of a positive electrode 4, a negative electrode 6 and an electrolyte layer in which a phosphate compound is included at least in one of a positive electrode active material, a negative electrode active material and a solid electrolyte. It is preferable that the solid electrolyte has a deliquescent property, and the layered product is formed into an electrode structure 10 excelling in charge-discharge characteristic by reducing interfacial impedance by executing such electricity application. A battery assemblying process can be carried out in the atmospheric environment.
