Abstract

Thin and Sb‐doped films have been prepared from aqueous colloidal solutions containing and precursors by the dip‐coating technique. The films are characterized as small grains (40 to 70 Å) and exhibit the ability to uptake reversibly Li⁺ and H⁺ ions from solutions of (0.1 M) in acetonitrile (AN) or water, (0.1 M) and (0.001 to 0.01 M). It was found that Sb‐doped (7 a/o Sb) films thicker than 100 nm exhibit about three times greater (de)inserted charges as compared to the undoped films. With regard to the amount of (de)inserted charge (up to 8 mC/cm²), Sb‐doped films are suitable for mixed electronically conductive, ion‐storage electrodes in electrochromic devices.
