Abstract
Organic electrolytic solutions and lithium batteries using the organic electrolytic solutions are provided. One organic electrolytic solution includes a lithium salt, a mixed organic solvent consisting of a high-dielectric constant solvent and a low-boiling point solvent, and a compound represented by Formula 1 or 2 as an additive. The organic electrolytic solution and the lithium battery using the organic electrolytic solution may inhibit the reductive cleavage reaction of a polar solvent, thereby increasing capacity retention of the battery, and improving charge-discharge efficiency and battery lifetime.
