      abstract     = {Ionic liquids (ILs) are considered to be suitable
                      electrolyte components for lithium-metal batteries.
                      Imidazolium cation based ILs were previously found to be
                      applicable for battery systems with a lithium-metal negative
                      electrode. However, herein it is shown that, in contrast to
                      the well-known IL N-butyl-N-methylpyrrolidinium
                      bis[(trifluoromethyl)sulfonyl]imide ([Pyr14][TFSI]),
                      1-ethyl-3-methylimidazolium
                      bis[(trifluoromethyl)sulfonyl]imide ([C2MIm][TFSI]) and
                      1-butyl-3-methylimidazolium
                      bis[(trifluoromethyl)sulfonyl]imide ([C4MIm][TFSI]) are
                      chemically unstable versus metallic lithium. A lithium-metal
                      sheet was immersed in pure imidazolium-based IL samples and
                      aged at 60 °C for 28 days. Afterwards, the aged IL
                      samples were investigated to deduce possible decomposition
                      products of the imidazolium cation. The chemical instability
                      of the ILs in contact with lithium metal and a possible
                      decomposition starting point are shown for the first time.
                      Furthermore, the investigated imidazolium-based ILs can be
                      utilized for lithium-metal batteries through the addition of
                      the solid–electrolyte interphase (SEI) film-forming
                      additive fluoroethylene carbonate.},
