    摘要： An organic electrolytic solution and a rechargeable lithium battery comprising the same is provided. The organic electrolytic solution contains a lithium salt and an organic solvent mixture. The organic solvent mixture is comprised of a solvent with high permittivity, a solvent with a low boiling point, and a cyclic organic compound having at least an oxy-carbonyl group and having a ring structure of 6 units or more. The organic electrolytic solution helps to increase reduction decomposition stability in the lithium battery using the same. As a result, the irreversible capacity of the lithium battery at a first cycle decreases and charge/discharge efficiency and lifespan of the lithium battery increases. In addition, the battery thickness is maintained within a specific range at room temperature after formation and standard charging, which improves the reliability of the lithium battery.

    摘要： 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 high dielectric constant solvent and a low boiling point solvent; and a carbonate or oxalate derivative having at least one substituted or unsubstituted cyano group. The organic electrolytic solution and the lithium battery employing the same have improved reductive decomposition stability, thereby decreasing an irreversible capacity after a first cycle and improving the charge/discharge efficiency and lifespan of the battery. The lithium battery has non-varying chemical properties at room temperature and a uniform thickness after standard charging, and thus has high reliability.

    摘要： An organic electrolytic solution including a lithium salt, an organic solvent, and a compound represented by the formula and a lithium battery employing the organic electrolytic solution. Groups Z1 and Z2 are each, independently, a cyano group, an isocyano group, a substituted or unsubstituted dicyanoethylphosphino group, or a substituted or unsubstituted dialkoxyphosphoryloxy group. Groups R1 through R4 are described fully in the Description. The organic electrolyte solution inhibits decomposition of an electrolytic solution and elution or precipitation of metal ions, and thus the lithium battery including the organic electrolytic solution has excellent cycle characteristics and lifetime characteristics.
