The present invention provides a method for producing a non-aqueous alkali metal power storage element, which includes applying a voltage to a non-aqueous alkali metal power storage element precursor in which a positive electrode precursor, a negative electrode, a separator, and a non-aqueous electrolyte solution are accommodated in an outer casing a voltage applying step in which the positive electrode active material layer of the positive electrode precursor contains a positive electrode active material and an alkali metal compound other than the positive electrode active material, (1) before or during the voltage applying step, the precursor is subjected to external Pressurizing; (2) heating the precursor before or during the voltage applying step; (3) performing a constant voltage on the precursor after the constant current charging of the precursor during the voltage applying step charging; (4) the C rate of the constant current charging is 1.0 times to 100.0 times the discharge capacitance (Ah) of the obtained non-aqueous alkali metal storage element; and (5) the voltage value of the constant voltage charging is 4.20 above V. |
