ABSTRACT:
An electrochromic cell of the present invention may include a first electrically conducting transparent electrode bonded to an electrochemically formed first electrochromic electrode on the surface of the electrode; a second electrically conducting transparent electrode bonded to an electrochemically formed second electrochromic electrode on the surface of the second electrode and a transparent gel polymer electrolyte formed from one or more macromonomers mixed with a plasticizer and an electrolyte salt, the gel polymer containing ionic liquids in contact with both the first and second electrochromic electrodes; the first and second electrochromic electrodes are separated from each other.
