      abstract     = {In this work, we present a comprehensive study on the
                      effect of adding different conductive salt additives
                      including LiPF6, LiBF4 and LiDFOB, as well as the
                      fluorinated solvent additive methyl difluoroacetate (MDFA)
                      to a bis(fluorosulfonyl)imide (FSI)-based ionic liquid (IL)
                      electrolyte, i.e. Pyr14FSI/LiFSI, to protect the Al current
                      collector (ACC) from anodic dissolution and, thus, enable
                      reversible charge/discharge cycling in a high performance
                      dual-ion cell. Chronocoulometry and scanning electron
                      microscopy measurements were conducted to evaluate the
                      specific ACC passivation ability of each electrolyte.
                      Furthermore, the influence of these additives on anion
                      intercalation behavior into the graphite positive electrode
                      with special emphasis on the Coulombic efficiency (CE),
                      reversible capacity, as well as capacity retention is
                      presented. Overall, we can show that the addition of small
                      amounts of LiPF6, LiBF4 and MDFA (0.5 $wt\%)$ into the
                      FSI-based IL electrolyte significantly increases the overall
                      cell performance, whereas LiDFOB as electrolyte additive
                      deteriorates the dual-ion cell performance. In addition, an
                      excellent cycling performance for 1000 cycles is obtained
                      for the Pyr14FSI electrolyte having 5 $wt\%$ LiPF6,
                      displaying an average reversible capacity of 40 mAh g−1, a
                      CE exceeding $98\%$ and a capacity retention of $91\%,$
                      which has not been reported so far.},
