PURPOSE: A nonaqueous electrolyte solution and a lithium battery employing the electrolyte solution are provided, to improve the stability of a lithium metal and the ion conductivity of lithium ions. CONSTITUTION: The nonaqueous electrolyte solution comprises a lithium salt; 100 parts by weight of an organic solvent; and 0.01-5 parts by weight of at least one compound represented by the formula 1, wherein R1 is H, a halogen atom, OH, a substituted or unsubstituted alkyl, alkoxy or alkenyl group, a substituted or unsubstituted aryl or aryloxy group of C6-C30, a substituted or unsubstituted heteroaryl or heteroaryloxy group of C2-C30, or R3-O-C(=O)- (wherein R3 is H, a halogen atom, a substituted or unsubstituted alkyl or alkenyl group of C1-C20, a substituted or unsubstituted aryl group of C6-C30, or a substituted or unsubstituted heteroaryl group of C2-C30); and R2 is H, a halogen atom, a substituted or unsubstituted alkyl or alkenyl group of C1-C20, a substituted or unsubstituted aryl group of C6-C30, or a substituted or unsubstituted heteroaryl group of C2-C30. The lithium battery comprises a cathode; an anode; a separator placed between the anode and the cathode; and the nonaqueous electrolyte solution. |
