The invention includes many applications for electrochromic devices that require neutral colors and patterned electrodes. It uses novel materials, ways of making the materials, device configurations and applications. In one aspect, the device also includes electrical leads (), transparent conductor layers (), patterned EC layers (), an etch line () and a substrate ().

Electrochromic devices

Electrochromic devices incorporate reversible oxidizers to improve device kinetics, incorporate counterelectrodes composed of an alkali metal oxide and vanadium oxide to improve stability, and doped tungsten or molybdenum oxide in the electrochromic layer to improve UV durability.

An electrochromic device is disclosed having a selective ion transport layer which separates an electrochemically active material from an electrolyte containing a redox active material. The devices are particularly useful as large area architectural and automotive glazings due to there reduced back reaction.

An electrochromic device is disclosed having a conducting electrode opposing a counter conducting electrode with an electrochemically active polymeric layer disposed on an opposing surface of one of said electrodes and an electrolyte containing at least one redox active material contactingly disposed between the electrochemically active layer and an other opposing surface of one of said electrodes, wherein at least one of the electrodes is transparent. Also disclosed is an electrochromic device that exhibits low light transmission or reflectivity with no applied potential or after removal of an applied potential.
