Abstract:
An electrolyte for a lithium secondary battery is prepared by injecting a gas additive having a higher reduction potential than a non-aqueous organic solvent into the non-aqueous organic solvent. The gas additive has a reduction potential ranging from 0.5 to 3.5 V based on the Li+ ions. Examples of gas additives include SO2, CO2, and N2O. In a secondary battery using the electrolyte to which the gas additive is not added, the non-aqueous organic solvent itself reacts with lithium ions at the beginning of the battery charging to form a solid electrolyte interface film and produces gases inside the battery, thereby increasing the internal pressure of the battery. However, in the electrolyte containing the gas additive of the present invention, the gas additive reacts with the lithium ions dissolved in the electrolyte to form a solid electrolyte interface film without producing gases that would increase the internal pressure of the battery. An electrolyte containing a gas additive prevents the production of gases, which increases the internal pressure of the battery and thus prevents the modification of the appearance of the battery. In addition, a lithium secondary battery prepared in accordance with the present invention has excellent discharge properties, cycle life and stability.
