METHOD OF MANUFACTURING POSITIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE BATTERY, THE NONAQUEOUS ELECTROLYTE BATTERY, AND THE POSITIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a positive electrode for a nonaqueous electrolyte battery that can fully suppress unevenness of the surface of the positive electrode, able to inhibit the positive electrode from contacting the negative electrode, even if a solid electrolyte is fully made thin, and uses the solid electrolyte that can prevent deficiency of the solid electrolyte, and to provide a method of manufacturing the electrode.

SOLUTION: The method of manufacturing the positive electrode for nonaqueous electrolyte battery by using the solid electrolyte includes a precursor sol solution filling process to fill a precursor sol solution of a positive electrode material with a positive electrode active material powder as a main substance in the concave part on the surface of a molding having unevenness on its surface; and a heat treatment process to heat-treat the molding filled with the precursor sol solution. The positive electrode manufactured by this manufacturing method uses the nonaqueous electrolyte battery, where the surface filled with the precursor sol solution of the positive electrode material is arranged to face the solid electrolyte and also uses a sintered body as the molding.
