专利汇可以提供Ammonia-treated electrochromic (ec) electrodes专利检索，专利查询，专利分析的服务。并且Method for forming a counter-electrode or imaging area in an electro-optical data display and imaging device, and the electrode and imaging areas formed. An electrochromic data display and imaging device may be formed by sandwich arrangement of the imaging area, the counter-electrode area with a suitable layer between. The device exhibits superior electrochromic reversability and improved speed and cell life over prolonged coloration and erase cycles.，下面是Ammonia-treated electrochromic (ec) electrodes专利的具体信息内容。

权利要求

1. A VARIABLE LIGHT TRANSMISSION DEVICE WHICH COMPRISES TWO LAYERS, ONE AN AMMONIA TREATED IMAGING PERSISTENT ELECTROCHROMIC MATERIAL, AND THE OTHER OF A COUNTERELECTRODE SEPARATED BY AN ELECTROLYTE LAYER DISPOSED BETWEEN A PAIR OF CONDUCTIVE ELECTRODES.

2. The device of claim 1, wherein said counterelectrode is a persistent electrochromic material.

3. The device of claim 2, wherein the presistent electrochromic materials in each said layer are identical.

4. The device of claim 2 wherein either one or both of said electrochromic imaging layer or counterelectrode is treated with ammonia.

5. The device of claim 1, wherein at least one of said electrodes is substantially transparent.

6. The device of claiM 5 wherein said persistent electrochromic material is tungsten oxide.

7. A process which comprises subjecting the device of claim 1 to electric current flow of alternating polarity whereby coloration and erase cycles are obtained without change in voltage-time characteristics.
