Beschreibung
Zusammenfassung:	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 organic electrolytic solution includes a first lithium salt, a second 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. The second lithium salt includes at least one selected from LiCF3SO3, Li(CF3SO2)2N, LiC4F9SO3, Li(FSO2)2N, and LiN(CxF2x+1SO2)(CyF2y+1SO2) where 2≤x≤20 and 2≤y≤20.
