ABSTRACTAll solid state electrochromic smart windows with the configuration glass/ITO/WO3/electrolyte/TiO2-CeO2/ITO/glass have been realized. These devices have potential applications in architectural and automotive fields to regulate the transmission and reflection of the radiant energy. The ion storage electrode TiO2–CeO2 have been realized by sol-gel process and its electrochemical properties are studied as a function of various parameters (thickness, heat treatment, etc.). The electrochemical and optical performances of two cells are reported.

CeO2-TiO2 sols and films were prepared by sol-gel method. The precursor sols consist of a mixture of cerium nitrate hexahydrate Ce(NO3)3·6H2O, butyl titanate Ti(OC4H9)4 and anhydrous ethanol CH3CH2OH. The films were deposited using the dip-coating technique and calcined at 310 °C in an oxygen atmosphere. The effects of the molar ratios of cerium to titanium（0.55:1, 0.70:1, 0.85:1, 1:1）on the microstructure and properties of (CeO2)x-TiO2 films were investigated. The surface morphology, electrochemical performance and optical property were characterized by FE-SEM, cyclic voltammetry (CV) and UV-Visible spectrometer, respectively. The results show that the properties of the films are tightly related to cerium to titanium ratio. When the molar ratio of cerium to titaniumis 0.85:1, the ion storage capacity value of CeO2-TiO2 film is 19.99mC/cm2, whereas the pure TiO2 film is 11.52mC/cm2. The stability tests and optical measurements confirm that the developed CeO2-TiO2 films can be use as ion storage-counter eletrodes in electrochromic devices.

AbstractLithium aluminum titanium phosphate (LATP) is known to have a high Li-ion conductivity and is therefore a potential candidate as a solid electrolyte. Via sol-gel route, it is already possible to prepare the material at laboratory scale in high purity and with a maximum Li-ion conductivity in the order of 1·10−3 s/cm at room temperature. However, for potential use in a commercial, battery-cell upscaling of the synthesis is required. As a first step towards this goal, we investigated whether the sol-gel route is tolerant against possible deviations in the concentration of the precursors. In order to establish a possible process window for sintering, the temperature interval from 800 °C to 1100 °C and holding times of 10 to 480 min were evaluated. The resulting phase compositions and crystal structures were examined by X-ray diffraction. Impedance spectroscopy was performed to determine the electrical properties. The microstructure of sintered pellets was analyzed by scanning electron microscopy and correlated to both density and ionic conductivity. It is shown that the initial concentration of the precursors strongly influences the formation of secondary phases like AlPO4 and LiTiOPO4, which in turn have an influence on ionic conductivity, densification behavior, and microstructure evolution.
