    摘要： An electrolyte for a lithium secondary battery is provided. The electrolyte improves battery safety, high temperature storage characteristics, and electrochemical properties of lithium batteries. The electrolyte comprises at least one lithium salt and a non-aqueous organic solvent comprising a cyclic carbonate and a lactone-based compound. The lactone based compound comprises substituents selected from the group consisting of alkyl groups, alkenyl groups, alkynyl groups, aryl groups, and combinations thereof. A lithium battery is also provided, which comprises a negative electrode capable of intercalating/deintercalating lithium, a positive electrode capable of intercalating/deintercalating lithium, and an inventive electrolyte.
