Abstract
The specification discloses a method for coating a substrate with electrochromic coatings by dipping a substrate having a conductive surface into, or spraying, or spin coating with, a solution prepared by reacting an anhydrous halide of an electrochromically active transition metal with a C1 to C5 anhydrous alcohol, most preferably under a stream of inert gas, at 0 to 80 degrees C. The dipped substrate is removed at a rate necessary to give a desired thickness, and the resulting coating is dried and hydrolyzed and further condensed to create an electrochromically active coating.
