Excellent performance was achieved by replacing the conventional alkyl carbonate solvents in the electrolyte solutions by fluorinated cosolvents. Replacement
In FDEEs with 1–5 fluorine atoms, the magnitude of the first peak in Li +-F RDF is smaller than that of the Li +-O RDF. This suggests that fluorine atoms in FDEEs can provide a less dominant solvation to lithium ions. For FDEEs with 6 fluorine atoms, the peak magnitude becomes comparable for Li +-O and Li +-F RDFs. This means fluorine and
