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
