METHOD FOR MANUFACTURING NONAQUEOUS ELECTROLYTIC SOLUTION SECONDARY BATTERY, AND NONAQUEOUS ELECTROLYTIC SOLUTION SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a nonaqueous electrolytic solution secondary battery having good battery characteristics by reducing the heat damage to a positive electrode at the time of baking, and a nonaqueous electrolytic solution secondary battery manufactured by the method.

SOLUTION: The method for manufacturing a nonaqueous electrolytic solution secondary battery with an inorganic solid electrolyte covering a positive electrode active material surface comprises: a preliminary baking step for preliminarily baking a precursor of the inorganic solid electrolyte at a temperature below the glass transition temperature of the inorganic solid electrolyte; a covering step for covering the surface of the positive electrode active material with the inorganic solid electrolyte precursor subjected to the preliminary baking; and a regular baking step for regularly baking the positive electrode active material at a temperature of the glass transition temperature or higher after the covering step.
