Nonaqueous electrolytic solution and nonaqueous electrolyte battery

A nonaqueous electrolytic solution comprising:

• an electrolyte,
• a nonaqueous solvent, and
• a compound represented by at least one formula selected from the group consisting of Formula (2) and Formula (3),
• wherein for Formula (2), R11 and R12 are each independently selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl group, an alkenyl group, an aryl group, an aralkyl group, an alkoxyalkyl group, and a group represented by Ra—O— in which Ra represents an alkyl group, an alkenyl group, an aryl group, an aralkyl group, or an alkoxyalkyl group, wherein each of R11 and R12 has at most 12 carbon atoms;
• and R15 represents an alkyl group having 1 to 12 carbon atoms, optionally substituted by a halogen atom, an alkenyl group having 2 to 12 carbon atoms, optionally substituted by a halogen atom, an aryl group having 6 to 12 carbon atoms, optionally substituted by a halogen atom, or an aralkyl group having 7 to 12 carbon atoms, optionally substituted by a fluorine atom;
• and
• wherein for Formula (3), R21 to R24 are each independently selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl group, an alkenyl group, an aryl group, an aralkyl group, an alkoxyalkyl group, and a group represented by Rb—O— in which Rb represents an alkyl group, an alkenyl group, an aryl group, an aralkyl group, or an alkoxyalkyl group, wherein each of R21 to R24 has at most 12 carbon atoms;
• R25 represents an alkyl group having 1 to 12 carbon atoms, optionally substituted by a halogen atom, an alkenyl group having 2 to 12 carbon atoms, optionally substituted by a halogen atom, an aryl group having 6 to 12 carbon atoms, optionally substituted by a halogen atom, or an aralkyl group having 7 to 12 carbon atoms, optionally substituted by a halogen atom;
• and r is an integer of 0 to 6, provided that when both R21 and R22 are alkoxy groups, r is an integer of 1 to 6, and at least one of R23 and R24 represent a group other than a hydrogen atom.
