ELECTROLYTES FOR LITHIUM METAL BATTERIES

Aspects of the disclosure include lithium metal batteries having fluorinated diacyl acetamides as the electrolyte solvent and methods of manufacturing the same. An exemplary vehicle includes an electric motor and a battery pack electrically coupled to the electric motor. The battery pack includes a battery cell that includes an anode current collector, an anode active material layer in direct contact with a surface of the anode current collector, a cathode current collector, a cathode active material layer in direct contact with a surface of the cathode current collector, and a liquid electrolyte over the cathode active material layer. The liquid electrolyte includes a lithium salt dissolved in an organic solvent. The organic solvent includes a fluorinated diacyl acetamide having an N-acetyl group coupled to a first functional group, a second functional group, and a third functional group.
