      abstract     = {In order to put oxide-based solid-state batteries into
                      practice (Figure 1), systematic investigations were carried
                      out to answer questions of chemical stability between
                      solid-state electrolyte and electrode materials [Miara,
                      2016]. In addition to these results, it will be described
                      how H2O and CO2 can affect solid electrolytes. Findings of
                      various analysis techniques, especially depth-resolved
                      methods like nuclear reaction analysis, Rutherford
                      backscattering spectrometry, and secondary ion mass
                      spectrometry, and raising issues will be presented and
                      discussed in this talk. Figure 1: Oxide-based bulk
                      solid-state battery based on LiCoO2 / Li7La3Zr2O12 mixed
                      cathode, Li7La3Zr2O12 electrolyte, and Li metal anode.Up to
                      now, research has shown that Li7La3Zr2O12 garnets (LLZ) and
                      Lithium phosphorus oxynitrides (LiPON) are apparently the
                      only electrolyte materials that can resist the low reduction
                      potential of metallic Lithium as well as high
                      electrochemical potentials up to about 5 V vs. Li/Li+.
                      Lithium ion conductors based on LLZ are particularly
                      promising solid electrolytes for solid-state Lithium
                      batteries due to their high Lithium ion conductivity.
                      However, the implementation into a practical battery cell is
                      impeded by challenges arising from material processing which
                      are partially associated with high temperature heat
                      treatments [Uhlenbruck, 2016; Tsai, 2019]. Moreover, the use
                      of metallic Lithium as anode is not as straightforward as
                      expected: Lithium metal filament growth can also occur
                      within ceramic electrolytes [Tsai, 2016].AcknowledgementsThe
