Zusammenfassung:	An additive for an electrolyte to be utilized in a rechargeable lithium battery. The electrolyte includes a non-aqueous organic solvent, a lithium salt, and the additive that has a halogen-substituted sulfonyl group and a heteroarene having unshared electron pairs. The additive may enhance or improve the room-temperature cycle-life characteristics and suppress or reduce an increase in resistance of the rechargeable lithium battery during high-temperature storage.
