Ceramic electrolytes are prepared through sintering processes which are carried out at high temperatures and require prolonged operating times, resulting unwelcome in industrial applications. We report a physicochemical characterization on hybrid, sodium conducting, electrolyte systems obtained by coating NASICON ceramic powders with the N-butyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide ionic liquid. The goal is to realize a ceramic-IL interface with improved sodium mobility, aiming to obtain a solid electrolyte with high ion transport properties but avoiding sintering thermal treatment. The purpose of the present work, however, is showing how simply combining NASICON powder and Py₁₄TFSI does not lead to any synergic effect on the resulting hybrid electrolyte, evidencing that an average functionalization of the ceramic powder surface and/or ionic liquid is needed. Also, the processing conditions for preparing the hybrid samples are found to affect their ion transport properties.

陶瓷电解质是通过烧结工艺制备的，该烧结工艺在高温下进行并且需要延长的操作时间，因此在工业应用中不受欢迎。我们报告了通过用N-丁基-N-甲基吡咯烷鎓双（三氟甲磺酰基）酰亚胺离子液体涂覆NASICON陶瓷粉末而获得的混合钠导电电解质体系的理化特性。目的是实现具有改善的钠迁移率的陶瓷-IL界面，旨在获得具有高离子传输性能但避免烧结热处理的固体电解质。但是，本工作的目的是说明如何简单地将NASICON粉和Py ₁₄结合在一起TFSI不会对所得混合电解质产生任何协同作用，证明需要陶瓷粉末表面和/或离子液体的平均功能化。而且，发现制备混合样品的加工条件会影响其离子传输性能。
