A highly fluorinated carbonate molecule-based electrolyte is introduced to enhance the electrochemical performance of lithium metal batteries. The applied bis(2, 2, 2-trifluoroethyl) carbonate (DFDEC) demonstrates impressive performance enhancement by stable oligomeric/LiF-based bi-layered surface modification of Li metal. Li symmetric cell cycling shows prolonged stable electroplating/stripping of Li metal because of the formation of a stable protective bilayer on the Li surface. Furthermore, the negatively shifted HOMO energy level of DFDEC enhances the anodic stability in the high-voltage region on the high-nickel-containing positive electrode surface. Both sophisticated electrochemical characteristics of the DFDEC lead to the enhanced cycle performance of the lithium metal cell.
