abstract = {Sodium all-solid-state batteries may become a novel storage
technology overcoming the safety and energy density issues
of (liquid-based) sodium ion batteries at low cost and good
resource availability. However, compared to liquid
electrolyte cells, contact issues and capacity losses due to
interface reactions leading to high cell resistance are
still a problem in solid-state batteries. In particular,
sulfide-based electrolytes, which show very high ionic
conductivity and good malleability, exhibit degradation
reactions at the interface with electrode materials and
carbon additives. A new group of solid electrolytes, i.e.,
sodium halides, shows wider potential windows and better
stability at typical cathode potentials. A detailed
investigation of the interface reactions of Na3SbS4 and
Na2.4Er0.4Zr0.6Cl6 as catholytes in cathodes and their
cycling performance in full cells is performed. X-ray
spectroscopy, time-of-flight spectrometry, and impedance
spectroscopy are used to study the interface of each
catholyte with a transition metal oxide cathode active
material. In addition, impedance measurements were used to
study the separator electrolyte Na3SbS4 with the catholyte
Na2.4Er0.4Zr0.6Cl6. In conclusion, cathodes with
Na2.4Er0.4Zr0.6Cl6 show a higher stability at low C-rates,
resulting in lower interfacial resistance and improved
cycling performance.},
