abstract = {Solid state electrolytes lead to intrinsic advantages in
terms of safety, electrochemical- and thermal stability.
However, the conductivity of lithium ion conducting solids
performs poorly compared to current liquid electrolyte
solutions. There are two approaches to overcome this
shortcoming. On one hand the conductivity of the materials
is improved by process tweaking and on the other hand the
electrolyte film thickness is reduced dramatically.
Especially for small electrical devices such thin film
battery systems seem promising. At IEK-1, thin film
batteries by PVD magnetron sputtering are fabricated. This
technology is highly compatible to complex multicomponent
materials and up scalable to industrial processing
standards. Our current research is focused on systems with
LiCoO2 cathodes and Li3+x PONX electrolyte. The high
temperatures required to crystalize some of the desired
phases cause diffusion, especially of lithium. ToF-SIMS
analysis is applied to monitor the lithium distribution in
our sample systems. The understanding of the interface
behavior is essential to identify relevant factors for
battery performance. The processing and first
characterization of our all-solid-state-thin-film battery
cells based on LiPON electrolyte is presented.},
