Abstract
An electrochromic device includes a first substrate spaced from a second substrate. A first conductive member is formed over at least a portion of the first substrate. A first electrochromic electrode comprising a tungsten oxide coating is formed over at least a portion of the first conductive member. A second conductive member is formed over at least a portion of the second substrate. A second electrochromic electrode is formed over at least a portion of the second conductive member. An ionic liquid is positioned between the first electrode and the second electrode. In one aspect of the invention, the ionic liquid can include nanoparticles of metals or metal oxides. In a further aspect of the invention, the second conductive member and second electrode can be formed by a single material.
