ELECTROLYTE AND LITHIUM BATTERY INCLUDING THE ELECTROLYTE

摘要

An electrolyte and a lithium battery comprising the electrolyte, a positive electrode, and a negative electrode are provided. The electrolyte comprises a lithium difluorophosphate (LiPO 2 F 2 ) a sultam-based compound, and an organic solvent. The electrolyte reduces the internal resistance increase rate of a lithium battery, and thus improves high-temperature stability of the lithium battery.
