      abstract     = {One important issue in future scenarios predominantly using
                      renewable energy sources is the electrochemical storage of
                      electricity in batteries. Among all rechargeable battery
                      technologies, Li-ion cells have the largest energy density
                      and output voltage today, but they have yet to be optimized
                      in terms of capacity, safety and cost for use as stationary
                      systems. Recently, sodium batteries have been attracting
                      attention again because of the abundant availability of Na.
                      However, much work is still required in the field of sodium
                      batteries in order to mature this technology.Sodium
                      superionic conductor (NASICON) materials are a thoroughly
                      studied class of solid electrolytes. In this study, their
                      crystal structure, compositional diversity and ionic
                      conductivity are surveyed and analysed in order to correlate
                      the lattice parameters and specific crystal structure data
                      with sodium conductivity and activation energy using as much
                      data sets as possible. Approximately 110 compositions with
                      the general formula
                      Na1+2w+x−y+zMw(II)Mx(III)My(V)M2−w−x−y(IV)(SiO4)z(PO4)3−z
                      were included in the data collection to determine an optimal
                      size for the M cations. In addition, the impact of the
                      amount of Na per formula unit on the conductivity and the
                      substitution of P with Si are discussed. An extensive study
                      of the size of the structural bottleneck for sodium
                      conduction (formed by triangles of oxygen ions) was carried
                      out to validate the influence of this geometrical parameter
                      on sodium conductivity.},
