1: A non-aqueous electrolytic solution, comprising:
a non-aqueous solvent comprising from 30 to 50 volume percent of a cyclic carbonate, based on a total volume of the non-aqueous solvent; from 0.5 to 1.5 M of at least one electrolyte selected from the group consisting of LiPF6 and LiBF4; from 0.01 to 3% by weight of succinonitrile or glutaronitrile, based on a total weight of the non-aqueous electrolytic solution; and from 0.2 to 3% by weight of at least one S═O group-containing compound selected from the group consisting of ethylenesulfite, 1,3-propanesultone, divinylsulfone, and propargyl methanesulfonate, based on a total weight of the non-aqueous electrolytic solution. |
