Summary: | An electrolyte includes: a lithium salt; a non-aqueous solvent; and a disulfonate compound represented by Formula 1:
wherein, in Formula 1, R 1 and R 2 are each independently a fluorine, a cyano group, a nitro group, or a methyl group substituted with at least one fluorine,
R 11 to R 14 are each independently a hydrogen, a deuterium, a fluorine, a hydroxyl group, a cyano group, a nitro group, a substituted or unsubstituted C 1 -C 10 alkyl group, a substituted or unsubstituted C 2 -C 10 alkenyl group, or a substituted or unsubstituted C 2 -C 10 alkynyl group,
a1 and a2 are each independently an integer of 1 to 5,
a11 and a12 are each independently an integer of 0 to 4, and
a sum of a1 and a11 is 5, and a sum of a2 and a12 is 5. |
