Multi-layer electrode for high contrast electrochromic devices

An electrochromic device, comprising:

• a first glass substrate spaced from a second glass substrate;
• a first transparent conductive electrode formed over at least a portion of the first substrate, the first electrode selected from the group consisting of indium tin oxide and fluorine doped tin oxide;
• a polymeric anode formed over at least a portion of the first conductive electrode, wherein the polymeric anode comprises polyaniline;
• a second transparent conductive electrode formed over at least a portion of the second substrate, the second electrode selected from the group consisting of indium tin oxide and fluorine doped tin oxide;
• a multi-layer polymeric cathode formed over at least a portion of the second conductive electrode, wherein the polymeric cathode comprises a first cathodic polymer formed over at least a portion of the second conductive electrode and comprising poly(3-octylthiophene-2,5-diyl) and a second cathodic polymer formed over at least a portion of the first cathode polymer and comprising at least one of poly(3,4-(2′,2′-dimethylpropylene)-dioxythiophene) or poly(2,3-dihydrothieno [3,4-b]-1,4 dioxin);
• and
• an ionic liquid positioned between the anode and the cathode.
