Claim 10:
11. A method for preparing the charge balancing thin film of the electrochromic device of claim 1, comprising:
preparing a suspension containing VO2 nanostructures by adding a soluble vanadium salt solution into a ZnO nanoparticle suspension to form a VO2 nanostructure suspension;
performing a first oxidation step to transform a portion of V4+ in the VO2 nanostructure suspension to V5+ with the presence of a V5+ precursor to form a VOx suspension;
centrifuging the VOx suspension to obtain a resulting sediment and re-dispersing the resulting sediment in a neutral polar solvent to form a VOx solution; and
preparing a VOx thin film by a coating method with the VOx solution.
