Abstract

New organic-inorganic hybrid crystalline electrolytes comprised of 12-phosphotungstic acid (PWA) and the ionic liquid [1-butyl-3-methylimidazole][bis-(fluoromethanesulfonyl)amide] ([BMIM][TFSI]) with high thermal stability and high ion conductivity at high temperatures were obtained. In the new hybrids, there was a strong interaction between [BMIM]⁺ of the ionic liquid and PWA. The hybrids were very stable up to about 400 °C and showed a high ion jump during heating and cooling processes. Based on results from TG-DTA, DSC, and NMR spectroscopy, the ion jump was due to melting and solidification of the hybrid. The structures of powder and single-crystal samples of the hybrids were also studied. The chemical formula of the hybrid in the single crystal was determined to be PW₁₃C₃₂H₅₆O₅₄N₈S_0.16F_0.26. This is nearly the same as those determined from the powder samples. By analyzing single-crystal X-ray diffraction (XRD) data, the hybrid was determined to crystallize in the space group Pca2₁ with the lattice constants a = 18.316(3), b = 18.327(3), and c = 16.657(3) Å. The powder XRD data of the hybrid were assigned.
