      abstract     = {A major drawback of conventional Li-ion batteries is the
                      use of organic liquid electrolytes. As an alternative,
                      batteries with solid lithium conducting electrolytes are
                      investigated. One of the promising oxide materials is the
                      garnet-structured Li7La3Zr2O12 (LLZ) with a competitive
                      Li-ion conductivity of about 10-4 S/cm. Furthermore, the
                      material has a good thermal stability (up to 1250°C), is
                      chemical compatible to metallic lithium, and
                      electrochemically usable up to 8V vs. Li/Li+. The structural
                      stability and ion conduction performance can be improved by
                      partial substitution (e.g. Al, Ta, Y). Furthermore, the
                      sintering temperature, required to achieve the high
                      conductive cubic phase, is reduced by doping. An additional
                      approach is to reduce the thickness of the electrolyte layer
                      to increase battery performance. At IEK1, we investigate two
                      main approaches for solid state electrolyte fabrication.
                      Very thin layers are synthesized by PVD. The aim is to
                      achieve a thin film battery in the range of a few
                      micrometers. For large scale fabrication of functional
                      layers tape casting of LLZ is investigated.},
