Aditya Sekhar, Nikesh Lilani, M. Dinachandra Singh

AI总结:

本文通过固态反应制备Na3Zr2Si2PO12-NaI复合材料,发现4% NaI取代可使200°C下离子电导率提升一个数量级,并揭示Na-Si-P-O-I相互作用导致玻璃相形成。

摘要:

通过固态反应路线成功制备了高离子导电钠超离子导体Na3Zr2Si2PO12-NaI复合材料。随着NaI含量的增加,离子电导率发生显著变化。含4% NaI的复合材料在200°C时表现出约3×10⁻⁴ Ω⁻¹cm⁻¹的最大离子电导率,与原始样品相比提高了一个数量级。进一步的晶体结构和表面形貌分析还揭示了由于Na-Si-P-O-I相互作用的存在而形成了玻璃相。

英文摘要:

The high ionic conducting sodium superionic conductor Na3Zr2Si2PO12 -NaI composites have been prepared successfully via solid state reaction route. As the NaI content increases, the ionic conductivity significantly changes. The composites with 4% NaI show a maximum ionic conductivity of ~ 3 x 10-4 Ω-1cm-1 at 200oC which is one order of magnitude rise as compared to pristine sample. Further crystal structure and surface morphology also reveal the formation of a glassy phase due to the presence of Na-Si-P-O-I interaction.
