Patent ID: 7684103

Claim:
An electrochromic device, comprising: at least one substantially transparent substrate having an electrically conductive material associated therewith; and an electrochromic medium which comprises: at least one solvent; at least one anodic material; at least one cathodic material, wherein both of the anodic and cathodic materials are electroactive and at least one of the anodic and cathodic materials is electrochromic; and a spacing member which comprises: a first material, wherein the first material is selected from the group comprising an electroactive material, an anodic material, a cathodic material, a non-polymeric material, a non-redox active ionic salt, a polymeric material, a solvent, a light stabilizer, a redox buffer, and combinations thereof; wherein the first material is at least partially associated with an encapsulant, and wherein the spacing member at least substantially dissolves upon association with the at least one solvent.
