abstract = {Liquid organic electrolytes cause safety problems due to an
insufficient thermal and electrochemical stability. One
approach to avoid such disadvantages is the replacement of
the liquid electrolyte by a solid one. Next to sulfides and
phosphates, current research is focused on Li conducting
ceramic oxide materials like Li7La3Zr2O12 (LLZ), a promising
garnet-structured material with a Li ion conductivity of
about 10-4 S/cm. Li ion conductivity can increased by
partial substitution of Li or Zr. Since the ionic
conductivity is about two orders of magnitude lower compared
to liquid electrolytes, thin electrolyte layers are
necessary for a low internal resistance of the cell.
Complete thin film batteries based on a current collector
substrate, a thin cathode, LLZ electrolyte layer and Li or a
Li alloy thin film as anode are deposited by physical vapor
deposition techniques. The deposition conditions are
optimized for each compound and adjusted to the overall
system. The resulting thin film batteries are analyzed with
regard to electrochemical behavior, structural and
morphological properties and element distribution.},
