Electrochromic devices

Conventional electrochromic devices frequently suffer from poor reliability and poor performance. Improvements are made using entirely solid and inorganic materials. Electrochromic devices are fabricated by forming an ion conducting electronically-insulating interfacial region that serves as an IC layer. In some methods, the interfacial region is formed after formation of an electrochromic and a counter electrode layer. The interfacial region contains an ion conducting electronically-insulating material along with components of the electrochromic and/or the counter electrode layer. Materials and microstructure of the electrochromic devices provide improvements in performance and reliability over conventional devices. In various embodiments, a counter electrode is fabricated to include a base anodically coloring material and one or more additives.

Composite assemblies are described that can be switched from a transparent state to a non transparent state, and in some examples even switched between different colors/reflectivities in the non transparent state. Switching between these states can be initiated by application of an electrical current to Ag carbon nanotube yarns in contact with an electrochromic electrolyte. The carbon nanotube yarns increase the efficiency with which electrons are provided to an electrolyte.
