abstract = {In this work, we studied the deposition of garnet
electrolyte thin films in order to realize an
all-solid-state battery with high energy density. Therefore,
in a first step we investigated the stability of the garnet
Li5La3Ta2O12 with the spinel LiCoMnO4 in order to determine
the temperature window for a successful thin film deposition
on high-voltage spinels. A mixture of both materials showed
a thermal stability up to 600 °C, so that all-solid-state
batteries could be realized when the electrolyte is applied
at a low deposition temperature. The second part of the work
was the thin film deposition of Li5La3Ta2O12 by a sputter
deposition process. When a stoichiometric Li5La3Ta2O12
sputter target was used, the surface of the target showed a
depletion of lithium after several depositions, which leads
to decreasing Li content in the thin films. In order to
compensate the lithium loss we enriched the target with
LiOH∙H},
