This work elucidated the influence of NaF on the structure and ion conductivity of Na2O-Al2O3-P2O5-Nb2O5 (F-0) glass. The enhancement in ionic conductivity of F-0 glass due to the individual NaF substitution for equal mol% of Na2O, Al2O3 and P2O5 have been thoroughly studied. Irrespective of the substitution for any oxides, the addition of NaF increased the concentration of Al(O,F)6 and isolated the PO43- tetrahedral units. Impedance analysis has shown that the substitution of NaF for Al2O3 has lowered the activation energy and improved the ionic conductivity significantly, which demonstrates this glass composition to be a promising material for solid state sodium ion batteries.
