      abstract     = {The design and control of the solid electrolyte interphase
                      (SEI) is essential for the implementation ofrechargeable
                      lithium metal based batteries and has been a major research
                      theme of lithium metal electrodes forover 50 years. However,
                      research on an as-defined SEI is challenging due to the
                      inevitable presence of a nativepassivation layer (NPL),
                      commonly contaminating an in situ formed SEI and its
                      characteristics. Herein we presentan original study on an
                      uncontaminated SEI being an exclusive reaction product of
                      lithium and a liquid aproticelectrolyte, highlighting the
                      largely negative influence of the NPL on different SEI
                      characteristics and functionaladditive evaluation. A
                      preformed as-defined SEI (pSEI) was generated by an in-house
                      designed advanced pretreatmentmethod, ensuring high
                      reproducibility and exclusion of the NPL by cutting and
                      pressing lithiummetal in solution/electrolyte. The
                      implementation of a pSEI allows for a systematic study and
                      an uncloudedcomparison of the two common functional
                      additives vinylene carbonate (VC) and fluoroethylene
                      carbonate (FEC)in an equal molar setting. The introduction
                      of an as-defined SEI allowed to clearly distinguish between
                      enhancinginfluence on the SEI characteristics and full cell
                      performance by FEC and the largely negative effect of VC
                      ondifferent SEI characteristics.},
