METHOD OF MANUFACTURING NONAQUEOUS ELECTROLYTE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a nonaqueous electrolyte battery for manufacturing a nonaqueous electrolyte battery with a satisfactory yield.

SOLUTION: The method of manufacturing a nonaqueous electrolyte battery has the steps of: forming a positive electrode layer 1 including a positive electrode active material made of an oxide; forming a negative electrode layer 2 including a negative electrode active material; forming a sulfide-based solid electrolyte layer (SE layer 3) disposed between the electrode layers 1, 2; and forming an intermediate layer 4 disposed between the positive electrode layer 1 and the SE layer 3. The method also has a step of performing UV ozone treatment to a surface of the intermediate layer 4 under an atmosphere containing oxygen before the step of forming the SE layer 3 after the step of forming the intermediate layer 4.
