Claim 17:
18. An electro-optic device, comprising:
an electro-optic element operable between a clear state and a darkened state, comprising:
a first substrate having a first surface and a second surface;
a second substrate having a third surface and a fourth surface;
a first electrically conductive layer positioned on the second surface;
a second electrically conductive layer positioned on the third surface;
a cathodic film including a cathodic component sequestered adjacent to a first electrically conductive layer by a first polymer matrix, wherein the cathodic film is positioned on the first electrically conductive layer; and
an anodic film including an anodic component sequestered adjacent to a second electrically conductive layer by a second polymer matrix, wherein the anodic film is positioned on the second electrically conductive layer, wherein the cathodic film and anodic film are configured such that a ratio of a molar amount of the cathodic component in the cathodic film to a molar amount of the anodic component in the anodic film is from greater than 1.1:1 to about 5:1.
