Firstly, it is difficult to densify CeO2 based solid electrolyte materials and a sintering temperature above 1600℃is required to prepare dense CeO2 based solid electrolyte materials by the conventional solid-state reaction method;Secondly, doped ceria are brittle materials and have weak mechanical strength, which would be susceptible to fracture due to thermal stresses and mechanical stresses during cell fabrication and operation; Thirdly, electronic conduction will be introduced because of the reduction of Ce4+ under low oxygen partial pressure, which would reduce the output voltage and output power of the cells.

In our research, thiophene derivant produced by desulfurization in the coking benzene was used as the polymer to provide the passing channel of the charges. The ionic liquid composition in poor performance after repeated use was made to prepare conductive material (resisting to static electricity) as an "electron-receiving" and "electron-giving" doping agent.

FT-IR spectra shows that the polyaniline is present primarily in the emeraldine salt form, and the polymeric chains interact with inorganic framework, most likely via V=O…HN hydrogen bonding. XRD,TG and DSC indicate that the lamellar structure of the V_2O_5 is preserved, PAn chains eliminate water form the interlamellar region and are partially inserted between the layers, and exist with extended-chain conformation owing to the confined environment.Electrochemical investigation in the range of 1.8~3.8V vs.
