The organic electrolyte solution according to the present invention contains halogenated benzene compounds such as 1-ureobenzene and 1-chlorobenzene. The halogenated benzene compound serves to lower the reactivity of the lithium metal surface, and has a high polarity, thereby preventing the binding of lithium ions and sulfide anions. Therefore, the solubility of sulfide increases in the electrolyte, thereby improving the utilization rate of sulfur, the charge / discharge efficiency characteristics of lithium ions, and the battery life characteristics. And the organic electrolyte solution of this invention can be used for the lithium sulfur battery and all the batteries which use a lithium metal electrode as an anode. |
