Nonaqueous electrolytic solution and nonaqueous electrolytic solution battery

A nonaqueous electrolytic solution battery comprising:

• a positive electrode that contains an oxide containing at least nickel as a positive electrode active material and has a content of nickel is in a range from 30% by mass to 100% by mass in a metal contained in the positive electrode active material;
• a negative electrode;
• and
• a nonaqueous electrolytic solution,
• wherein the nonaqueous electrolytic solution comprises:
• (I) a nonaqueous solvent;
• (II) a solute;
• and
• (III) a compound represented by General Formula [1]:
• R(SO2X)m [1],
• wherein R represents a monovalent group to a tetravalent group, each group containing at least one carbon atom, and each group optionally and independently comprises at least one moiety selected from the group consisting of hydrogen atoms, halogen atoms, unsaturated bonds, aromatic rings, oxygen atoms, and ester bonds,
• X represents a halogen atom or a linear or branched perfluoroalkyl group having 1 to 10 carbon atoms, and
• m represents an integer from 1 to 4, and when m represents an integer of 2 to 4, a plurality of X independently is the same or different from each other, wherein a content of (III) is in a range from 0.001% by mass to 1.8% by mass with respect to 100% by mass of a total amount of (I) to (III).
