      abstract     = {The film-forming electrolyte additive/co-solvent
                      fluoroethylene carbonate (FEC) can play a crucial role in
                      enabling high-energy-density lithium metal batteries (LMBs).
                      Its beneficial impact on homogeneous and compact lithium
                      (Li) deposition morphology leads to improved Coulombic
                      efficiency (CE) of the resulting cell chemistry during
                      galvanostatic cycling and consequently an extended cell
                      lifetime. Herein, the impact of this promising
                      additive/co-solvent on selected properties of LMBs is
                      systematically investigated by utilizing an in-house
                      developed lithium pretreatment method. The results reveal
                      that as long as FEC is present in the organic
                      carbonate-based electrolyte, a dense mosaic-like lithium
                      morphology of Li deposits with a reduced polarization of
                      only 20 mV combined with a prolonged cycle life is achieved.
                      When the pretreated Li electrodes with an FEC-derived
                      preformed SEI (pSEI) are galvanostatically cycled with the
                      FEC-free electrolyte, the described benefits induced by the
                      additive are not observable. These results underline that
                      the favorable properties of the FEC-derived SEI are
                      beneficial only if there is unreacted FEC in the electrolyte
                      formulation left to constantly reform the interphase layer,
                      which is especially important for anodes with high-volume
                      changes and dynamic surfaces like lithium metal and
                      lithiated silicon.},
