Abstract
An electrochromic device including a first substantially transparent substrate having an electrically conductive material associated therewith; a second substrate having an electrically conductive material associated therewith; an electrochromic medium contained within a chamber positioned between the first and second substrates which includes at least one solvent, at least one anodic material, and at least one cathodic material, wherein the first and second substrates are substantially uniformly spaced apart by a spacing member comprising a non-polymeric material which substantially dissolves upon association with the at least one solvent.

45. 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. - View Dependent Claims (46, 47, 48, 49)
