ABSTRACT:
An electrochromic medium for use in an electrochromic device comprising: at least one solvent; an anodic electroactive material; a cathodic electroactive material, wherein at least one of the anodic and cathodic electroactive materials is electrochromic; and a current-reducing additive, wherein the current-reducing additive comprises a polymer present in an effective concentration to materially reduce the current of the electrochromic medium upon application of an electrical potential, relative to an electrochromic medium without the current-reducing additive, while maintaining an electrochromic medium viscosity which facilitates acceptable production rates without a problematic degree of seal or other device component failure.
