abstract = {LATP sheets with LiF and SiO 2 addition prepared by tape
casting aselectrolytes for solid-state batteries were
characterized regardingconductivity, microstructure and
mechanical properties aimingtowards an optimized
composition. The use of additives permitteda lowering of the
sintering temperature. Rietveld analyses of thesamples with
additives revealed a phase mixture of NaSICONmodifications
crystallizing with rhombohedral and orthorhombicsymmetry as
a superstructure with space group Pbca. It seemsthat LiF
acts as a sintering additive but also as a mineralizer for
thesuperstructure of LATP. As general trend, higher LiF to
SiO2 ratiosled to lower porosities and higher values of
elastic modulus andhardness determined by indentation
testing, but the presence ofthe orthorhombic LATP leads to a
decrease of the ionic conductivity.Micro-pillar testing was
used to assess the crack growth behaviorrevealing weak grain
boundaries.},
