Abstract:
A lithium battery includes a cathode including a cathode active material; an anode including an anode active material; and an organic electrolytic solution between the cathode and the anode, wherein the anode active material includes natural graphite and artificial graphite, an amount of the artificial graphite being about 50 wt % or more based on a total weight of the anode active material, and the organic electrolytic solution includes: a first lithium salt; an organic solvent; and a bicyclic sulfate-based compound represented by Formula 1 below: wherein, in Formula 1, each of A1, A2, A3, and A4 is independently a covalent bond, a substituted or unsubstituted C1-C5 alkylene group, a carbonyl group, or a sulfinyl group, in which both A1 and A2 are not a covalent bond and both A3 and A4 are not a covalent bond.
