Abstract 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.

NaF对磷酸铝钠玻璃电解液离子电导率的影响

摘要 本工作阐明了 NaF 对 Na2O-Al2O3-P2O5-Nb2O5 (F-0) 玻璃结构和离子电导率的影响。F-0 玻璃的离子电导率由于单独的 NaF 替代等 mol% 的 Na2O、Al2O3 和 P2O5 而增强，这已得到深入研究。不考虑任何氧化物的替代，添加 NaF 会增加 Al(O,F)6 的浓度并分离 PO43-四面体单元。阻抗分析表明，用 NaF 代替 Al2O3 降低了活化能并显着提高了离子电导率，这表明这种玻璃组合物是一种很有前途的固态钠离子电池材料。
