Abstract
Ce0.5Ti0.5O2 ion storage films were prepared by using sol–gel routes employed butyltitanate(Ti(OC4H9)4) and cerium nitrate(Ce(NO3)3•6H2O) as main initial materials. Structural, optical and electrochemical properties were investigated by XRD, SEM, cyclic voltammetry curves and utraviolet visible spectroscopy in this work. Ce0.5Ti0.5O2 ion films contained crystallization CeO2 and amorphous TiO2, and had large ion storage capacity. Its injection of charge density was high to 12.01 mC•cm-2 and K value was 0.75. It had better cyclic reversibility and high transparency, which kept colorless and transparent during the whole injection and extraction process of Li+. Light insert ion storage films of Ce0.5Ti0.5O2 has important significance in the preparation of electrochromic device.
