The present invention provides an organic electrolyte comprising a lithium salt and an organic solvent, wherein the organic solvent comprises an alkoxy group-containing compound represented by the formula (1) and a lithium battery employing the same.n n n n n CH 3 O (CH 2 ) n CHR 1 R 2 n n n n n Wherein n is an integer of 1 to 5, R 1 and R 2 are a halogen atom, a hydroxyl group, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted carbon number, irrespective of each other An alkoxy group of 1 to 20, a substituted or unsubstituted aryl group of 6 to 30 carbon atoms, a substituted or unsubstituted aryloxy group of 6 to 30 carbon atoms, a substituted or unsubstituted heteroaryl group of 2 to 30 carbon atoms Or a substituted or unsubstituted heteroaryloxy group having 2 to 30 carbon atoms. The organic electrolytic solution of the present invention contains an alkoxy group-containing compound such as 1,1,3-trimethoxypropane (TMP), and further contains an organic compound containing a polyglyme and a dioxolane component. The stabilization effect of lithium metal is excellent and the charge and discharge efficiency of lithium is greatly improved by increasing the ion conductivity of lithium ions. Such an organic electrolyte is usefully applicable to lithium batteries and lithium sulfur batteries using lithium metal electrodes as anodes. |
