An electrolyte for a rechargeable lithium battery includes a non-aqueous organic solvent; a lithium salt; and an additive including vinylene carbonate, fluoroethylene carbonate, and a nitrile-based compound represented by Formula 1: wherein n ranges from 1 to 12 and R<SUB>1 </SUB>and R<SUB>2 </SUB>are independently a halogen, a hydrogen, or an alkyl group. Further, the alkyl group can be C<SUB>m</SUB>H<SUB>(2m+1)</SUB>, in which m ranges from 1 to 10. The electrolyte for a rechargeable lithium battery improves storage stability of the rechargeable lithium battery at a high temperature. And, a rechargeable lithium battery including the electrolyte has improved storage stability.
