Abstract
An organic electrolytic solution and a lithium battery employing the same are provided. The organic electrolytic solution includes a lithium salt, an organic solvent containing a first solvent having a high dielectric constant and a second solvent having a low boiling point, and a surfactant including a hydrophobic portion having an aromatic group. The organic electrolytic solution effectively prevents the electrolytic solution from contacting the anode, thereby suppressing side reactions on the anode surface and improving discharge capacity, charge/discharge efficiency, lifespan, and battery reliability.
