	abstract = {Ti-doped V oxide thin films were fabricated by electrochem. deposition on linear polyethylenimine (LPEI)-modified In Sn oxide-coated glass from mixed V oxide and Ti oxide solns. with different Ti concns. The as-prepd. films were studied by XRD, at. force microscopy (AFM), and XPS. The electrochem. behavior of the films was studied using cyclic voltammetry (CV) in 1.0 M LiClO4/propylene carbonate soln. Electrochromism of the oxide films upon Li-ion intercalation/deintercalation was studied by transmittance measurements during the CV process. The charge transfer resistance of the Ti-doped V oxide film was systematically analyzed with electrochem. impedance spectroscopy (EIS). The amorphous Ti-doped V oxide film contg. 4 mol\% Ti exhibited the highest transmittance contrast (Δ\%T = Tmax - Tmin) of \~51.1\%T, and coloration efficiency of 95.7 cm2 C-1 at 415 nm. By increasing the Ti content to 10 mol\%, the Ti-doped V oxide film exhibited high switching speed and good cycling reversibility reaching 80\% of coloring and bleaching time of 5 and 6 s, resp. Also, the transmittance contrast drops by only 10\% after 600 cycles in a two-electrode system. [on SciFinder(R)]},
