Electrochromic devices (ECDs) with WO3/PVB electrolyte/CeO2-TiO2 configuration were assembled and characterized. The ECDs revealed charge density values of 2.9 and 7.8 mC/cm2 with a cathodic/anodic ratio of 0.9 and 1.0 for the systems containing PVB-LiClO4 and PVB-LiI electrolytes, respectively. The electrochemical stability showed a decrease of charge density, from 7.8 to 3.7 mC/cm2 as a function of color/bleaching cycling being between 10 and 1,200th cycles for the ECD with PVB-LiI; and from initial 2.9 to 1.0 mC/cm2 after 48,000 cycles for the ECD with PVB-LiClO4. Moreover, a difference in transmittance of 30% between the ECD's colored and bleached states was also observed.
