      abstract     = {Na3V2(PO4)3 (NVP) is a promising electrode material for
                      sodium‐ion batteries. However, many of its electrochemical
                      properties like ionic conductivities have never been
                      systematically studied. In the present paper, a battery cell
                      with controlled morphology of NVP was prepared and the
                      electrochemical impedance spectra were measured at various
                      voltages. The ionic conductivity of NVP was calculated in
                      dependence on applied potentials. NVP has a total
                      conductivity of 1×10−6 S cm−1 at 2.9 V, which
                      decreases to 8×10−8 S cm−1 at 3.5 V. This low
                      conductivity, especially at higher voltages, influences the
                      performance of batteries with an NVP electrode, especially
                      by limiting the high‐rate cycling of solid‐state
                      batteries.},
