Claim 0:
1. An electrochromic device, comprising:
a first conductive layer;
a cathodically coloring layer comprising a cathodically coloring electrochromic material; and
an anodically coloring layer comprising an anodically coloring electrochromic material and one or more additives,
wherein the anodically coloring electrochromic material comprises an oxide of at least one metal selected from the group consisting of chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), rhodium (Rh), ruthenium (Ru), vanadium (V), and iridium (Jr), and
wherein at least one of the one or more additives comprises a material selected from the group consisting of cadmium (Cd), europium (Eu), mercury (Hg), lead (Pb), promethium (Pm), polonium (Po), radium (Ra), terbium (Tb), thorium (Th), thallium (Tl), and combinations thereof; and

a second conductive layer, wherein the cathodically coloring layer and the anodically coloring layer are positioned between the first and second conductive layers,
wherein the metal in the anodically coloring electrochromic material is present in the anodically coloring layer at an atomic ratio equal to or greater than an atomic ratio of the metal in the one or more additives.
