Nonaqueous secondary battery and method for producing nonaqueous secondary battery

A method of producing a nonaqueous secondary battery, the method comprising:

• preparing a nonaqueous secondary battery precursor;
• and
• charging and discharging the nonaqueous secondary battery precursor,
• wherein the nonaqueous secondary battery precursor comprises:
• a nonaqueous electrolyte solution that comprises a compound (A) represented by the following Formula (I);
• a positive electrode that comprises a positive electrode active material comprising a compound (B) represented by the following Formula (II);
• and
• a negative electrode, and
• wherein a content of the compound (A) is more than 0% by mass but less than 1.0% by mass with respect to a total amount of the nonaqueous electrolyte solution:
• wherein, in Formula (I), X+ represents a hydrogen ion, a lithium ion, a sodium ion, or a potassium ion:
• LiaNi(1-b-c)CobMncO2 (II)
• wherein, in Formula (II), 0.1≤a<1.3, 0.1<(1-b-c)<1.0, 0<b<0.6, and 0<c<0.6.
