abstract = {In conventional lithium ion batteries, the using of liquid
electrolyte is the bottleneck for improving its safety,
energy density and lifetime. Solid-state ion conductors are
the promising approach to overcome these limitations. Among
the solid Li ionic conductors, garnet structured
Li7La3Zr2O12 (LLZ) has attracted most attention due to their
high ion conductivity, wide electrochemical window versus
Li+/Li, chemically stable against metallic Li and inert to
oxygen which makes it easy for processing. Therefore, LLZ is
one of the most promising candidates for all-solid-state
batteries as well as Li-air and Li-sulfur battery
applications.The battery research activities at IEK-1 are
focused on applications in stationary and automotive systems
as well as miniaturized thin film cells. Physical vapor and
wet-chemical depositions are used for layers with thickness
of about one micrometer in thin film batteries. For bulk
batteries with layers, tape casting and screen printing is
used for material processing. The synthesized materials and
the fabricated cells have been analyzed with regard to their
morphology, stoichiometry, crystal phase composition and
electrochemical performances. The effect of deposition
parameters and substrates on layer growth as well as the
influence of microstructure architecture on the cell
performance will be discussed.},
