Rechargeable sodium-ion batteries have gained considerable interest as potential
alternatives to lithium-ion batteries, owing to their low cost and the wide
abundance of sodium. Vanadium phosphates have
shown high energy densities as cathode materials, but their Na-ion transport
and cation doping properties are not as yet fully understood. Here, we have combined
density functional theory calculations and molecular dynamics techniques to
study the diffusion, electronic properties and cation doping behaviour of the a-, b-
and aI-NaVOPO4
polymorphs. The data described here are ASCII files containing the diffusion coefficients of the three polymorphs at different temperatures and the computed voltage of the doped compounds. Calculations were carried out using the Vienna Ab-initio Simulation Package (VASP) and the LAMMPS code.

Research results based upon these data are published at http://doi.org/10.1021/acs.jpcc.8b07797
