The electrolyte for a lithium battery includes a non-aqueous organic solvent, a lithium salt, and an additive of the following Formula 1: wherein, X is O, S, CR<SUB>2 </SUB>or NR, where here R is H, a halogen, or an alkyl having a carbon number of less than or equal to 8, or neighboring alkyl groups are combined to each other to form a cycle or hetero cycle, Y<SUB>1</SUB>, and Y<SUB>2 </SUB>are the same or different from each other and selected from O, S, CR<SUB>2</SUB>, and NR, where here R is H, a halogen, or an alkyl having a carbon number of less than or equal to 8, or neighboring alkyl groups are combined to each other to form a cycle or hetero cycle, Y<SUB>3 </SUB>is S, CR<SUB>2</SUB>, or NR, where here R is H, a halogen, or an alkyl having a carbon number of less than or equal to 8, or neighboring alkyl groups are combined to each other to form a cycle or hetero cycle, and R<SUB>a </SUB>to R<SUB>d </SUB>are the same or different from each other and selected from H, a halogen, an alkoxy group having a carbon number of less than or equal to 8, or an unsaturated or saturated alkyl group having a carbon number of less than or equal to 8, neighboring alkyl groups are combined to each other to form a cycle or hetero cycle.
