      abstract     = {Lithium ion batteries (LIB) are representing a milestone in
                      electrochemical energy storage and are still the
                      state-of-the-art battery system for various mobile and
                      stationary energy storage applications. However, the
                      practical energy density of LIBs starts to reach an
                      asymptotic limit. Beside LIBs, an auspicious variety of
                      battery systems comprising a better option for specific
                      applications in terms of e.g. energy density, so
                      establishing a diversity of specific battery systems for
                      specific applications is a good strategy.[1] After initially
                      paving the way for the LIB, the lithium metal battery (LMB)
                      experiences a revival due to an outstanding theoretical
                      specific capacity (3 860 mAh g−1) and low electrochemical
                      potential (−3.04 V vs. SHE). However, continuous
                      electrolyte consumption, the formation of an inhomogeneous
                      SEI and high surface area lithium (HSAL), whose growth is
                      induced by the heterogeneous and fragile structure of the
                      SEI film, are still dominant challenges that need to be
                      overcome. The liquid electrolytes also deal with safety
                      issues like risk of leakage and flammability. The
                      combination of Li metal with solid polymer electrolytes
                      (SPE) could supress HSAL formation and avoid those safety
                      hazards. However, SPEs deal with poor ionic conductivity at
                      room temperature (10−8 S cm−1 ≤ σ ≤ 10−5 S
                      cm−1) and, additionally, it is necessary to control the Li
                      morphology during electrodeposition/dissolution to realize
                      high-energy all-solid-state batteries (ASSB) based on Li
                      metal anodes.[2,3]Several artificial protective coatings
                      have been proposed to improve the LMA/SPE interface by
                      facilitating the Li ion flux, promoting a homogeneous Li
                      electrodeposition/dissolution and protecting the LMA against
                      electrolyte degradation as well as enhancing the Li wetting
                      interface. The SPE induces a more flexible interphase that
                      withstands the volume change. Recently, metal oxides coated
                      by atomic layer deposition (ALD) have gained attention due
                      to a great thickness control, the possibility of monolayer
                      deposition as well as a consequential homogeneity of the
                      deposited protection layer. Furthermore, ALD is suitable for
                      roll-to-roll coatings which is feasible for industrial
                      application.[3,4]Herein, the setup of Li-metal-polymer
                      batteries (LMP® technology) commercialized by Blue
                      Solutions and applied in their "blue cars" (30 kWh, 100 Wh
                      kg-1) was modified in several points. Li metal was coated
                      with a metal oxide via atomic layer deposition (ALD) to form
                      an intermetallic phase as protective layer and to improve
                      the Li+ flux. The artificial protective coating at Li metal
                      was combined with a PEO- and/or polyether-based SPE and the
                      effect of the modifications on the electrochemical
                      performance in different ASSB setups was investigated and
                      characterized.[1] Placke, T.; Kloepsch, R.; Dühnen, S.;
