      abstract     = {All-solid-state sodium batteries are attractive due to the
                      abundance of sodium and advantageous for safe battery
                      operation by avoiding flammable organics and liquids and
                      suppressed dendrite formation. Currently, the lack of a
                      chemically stable sodium solid electrolyte with high ion
                      conductivity at room temperature is one of the challenges
                      for future development of sodium batteries. Herein, we
                      present a NaxCoO2/Nasicon/Na thin-film model sodium
                      solid-state battery using a Sc-substituted Nasicon solid
                      electrolyte with a high ionic conductivity of 4 × 10⁻³ S
                      cm⁻¹. The battery shows a high specific capacity of 150
                      mAh g⁻¹ at room-temperature and discharge rates of up to
                      6C. Excellent chemical stability of this solid electrolyte
                      at high voltages of up to 4.2 V increases the accessible
                      sodium (de)intercalation range and battery capacity. Direct
                      extraction of the interface resistances between the
                      electrode materials of the thin-film model cell using
                      electrochemical impedance spectroscopy gives a unique
                      opportunity of correlation the electrochemical performance
                      with properties of electrode materials and their
                      interfaces.},
