abstract = {NASICON-type solid electrolytes are promising materials for
novel solid-state-batteries aiming toward high energy
densities. Na1+xHf2Si2.3P0.7O10.85+0.5x with varying sodium
content as well as Sc- or Mg-doped and undoped
Na1+xZr2P3-xSixO12 were synthesized by solution-assisted
solid-state reaction. Microstructural and mechanical
characteristics as well as conductivities were investigated.
The electrochemical and microstructural properties of all
studied materials appear to be highly affected by the sodium
content glassy phase and secondary phase formation as well
as bloating. The mechanical properties of the specimens
depend mainly on microstructural characteristics. Our
findings indicate improved mechanical behavior is achieved
when bloating and secondary phase formation are inhibited.
However, possible influences of glassy phase content on the
material properties need to be further investigated.},
