An electrolyte solution for a non-aqueous electrolyte solution battery, comprising a non-aqueous solvent, a solute, and an additive for a non-aqueous electrolyte solution, wherein the additive is represented by any one of formula [1], formula [2], formula [3], and formula [4]:
- wherein, in the formula [1], formula [2], formula [3], and formula [4],
- X1 and X2 are each independently a fluorine atom or an organic group selected from the group consisting of a linear or branched alkyl group having 1 to 10 carbon atoms, a linear or branched alkoxy group having 1 to 10 carbon atoms, a linear or branched alkenyl group having 2 to 10 carbon atoms, a linear or branched alkenyloxy group having 2 to 10 carbon atoms, a linear or branched alkynyl group having 2 to 10 carbon atoms, a linear or branched alkynyloxy group having 2 to 10 carbon atoms, a cycloalkyl group having 3 to 10 carbon atoms, a cycloalkoxy group having 3 to 10 carbon atoms, a cycloalkenyl group having 3 to 10 carbon atoms, a cycloalkenyloxy group having 3 to 10 carbon atoms, an aryl group having 6 to 10 carbon atoms, and an aryloxy group having 6 to 10 carbon atoms, wherein the organic group optionally contains a fluorine atom, an oxygen atom, or an unsaturated bond;
- Y is a carbon atom or a sulfur atom;
- R1 and R2 are each independently an organic group selected from the group consisting of a linear or branched alkyl group having 1 to 10 carbon atoms, a linear or branched alkoxy group having 1 to 10 carbon atoms, a linear or branched alkenyl group having 2 to 10 carbon atoms, a linear or branched alkenyloxy group having 2 to 10 carbon atoms, a linear or branched alkynyl group having 2 to 10 carbon atoms, a linear or branched alkynyloxy group having 2 to 10 carbon atoms, a cycloalkyl group having 3 to 10 carbon atoms, a cycloalkoxy group having 3 to 10 carbon atoms, a cycloalkenyl group having 3 to 10 carbon atoms, a cycloalkenyloxy group having 3 to 10 carbon atoms, an aryl group having 6 to 10 carbon atoms, and an aryloxy group having 6 to 10 carbon atoms, wherein the organic group optionally contains a fluorine atom, an oxygen atom, or an unsaturated bond;
- R3 and R4 are each independently an organic group selected from the group consisting of a linear or branched alkyl group having 1 to 10 carbon atoms, a linear or branched alkenyl group having 2 to 10 carbon atoms, a linear or branched alkynyl group having 2 to 10 carbon atoms, a cycloalkyl group having 3 to 10 carbon atoms, a cycloalkenyl group having 3 to 10 carbon atoms, and an aryl group having 6 to 10 carbon atoms, wherein the organic group optionally contains a fluorine atom, an oxygen atom, or an unsaturated bond;
- and
