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