      abstract     = {Organic solvents undergo degradation reactions when in
                      contact with lithium metal. These reactions form a layer of
                      decomposition products that partly prevents further
                      electrolyte decomposition—passivation. Still, the chemical
                      processes in this system are complex and have not yet been
                      fully understood though it is of high relevance for lithium
                      metal batteries. Scanning Electrochemical Microscopy (SECM)
                      in feedback mode as well as GC-MS are used for analyzing the
                      interface as well as soluble decomposition products. SECM
                      data show that the native interface thickness on metallic
                      lithium from ethylene carbonate (EC) and ethyl methyl
                      carbonate (EMC) electrolyte solutions is reduced by approx.
                      $98\%$ by adding 5 $wt\%$ vinylene carbonate (VC) to the
                      solution. The addition of VC changed significantly the
                      dynamics of the growth of the deposition layer. GC-MS
                      studies of the EC:EMC electrolyte solution proof an ongoing
                      reaction of the metallic lithium with the electrolyte even
                      after several days. In comparison, the addition of VC
                      appears to stabilize the interface and no decomposition
                      products could be identified. It is concluded that the
                      addition of VC to the electrolyte solution from EC:EMC
                      prevents the trans-esterification of EMC by surface
                      passivation and not by scavenging alkoxides as claimed in
                      literature.},
