      abstract     = {The energy density of traditional lithium ion batteries
                      (LIB) based on graphite intercalation compounds as negative
                      active material is approaching the theoretical limit and are
                      restricting the increasing demand of high energy battery
                      systems for various mobile and stationary applications.[1]
                      Consequently, the implementation of active materials with
                      high specific energies became prerequisite for future
                      battery technologies. Therein, lithium metal is one of the
                      most promising anode active materials to replace
                      state-of-the-art graphite active materials, due to its high
                      theoretical capacity and low electrode potential.[2]However,
                      poor cycling performance, low Coulombic efficiency, and the
                      uncontrollable Li dendrite growth during lithium
                      electrodeposition/dissolution processes remain as
                      predominant challenges.[3]Several approaches were proposed
                      to eliminate dendrite formation by implementing a
                      mechanically and electrochemically stable artificial solid
                      electrolyte interphase or artificial protective coatings
                      (aPC) by in-situ or ex-situ surface modifications.[4] These
                      designed aPCs should feature an increased and uniform Li-ion
                      flux, mechanical robustness and/or protection against
                      electrolyte decomposition, during substantial volume changes
                      upon electrodeposition/dissolution. However, aPCs fail to
                      support long term cycling stability in lithium metal
                      batteries since they cannot cover all requirements.[5]
                      Therefore, it is crucial to design and understand dual- and
                      multilayer system that address multiple aforementioned
                      requisites.[6]In this contribution, a dual-protective
                      artificial layer is constructed on Li metal by physical
                      vapor deposition consisting of an intermetallic LiZn-layer,
                      providing a uniform Li-ion flux, and an inorganic
                      Li3N-layer, which is electron-blocking, thus reveal surface
                      protective properties. In addition to electrochemical
                      characterization, the Li electrodeposition/dissolution
                      behavior was investigated by cryo-FIB/SEM analysis to
                      unravel the mechanism behind the enhanced cycling stability
                      in symmetrical Li||Li cells and cells with a layered
                      oxide-based positive electrode.[1] R. Schmuch, R. Wagner, G.
