      abstract     = {Sodium–ion batteries are emerging as strong competition
                      to lithium–ion batteries in certain market sections. While
                      these cells do not use critical raw materials, they still
                      feature a liquid electrolyte with all its inherent safety
                      issues, like high flammability and toxicity. Alternative
                      concepts like oxide-ceramic-based all-solid-state batteries
                      feature the highest possible safety while still maintaining
                      competitive electrochemical performance. However, production
                      technologies are still in their infancy, especially for Na
                      all-solid-state batteries, and need to be urgently developed
                      to enable solid-state-battery technology using only abundant
                      raw materials. In this study, the additive-free production
                      of freestanding, undoped NaSICON separators via tape-casting
                      is demonstrated, having an extremely high total Na-ion
                      conductivity of up to 2.44 mS·cm−1 at room temperature.
                      Nevertheless, a strong influence of sample thickness on
                      phase purity as well as electrochemical performance is
                      uncovered. Additionally, the effect of self-coating of
                      NaSICON during high-temperature treatment was evaluated as a
                      function of thickness. While advantageous for increasing the
                      stability against Na-metal anodes, detrimental consequences
                      are identified when separator thickness is reduced to
                      industrially relevant values and mitigation measures are
                      postulated.},
