Abstract
Disclosed is an electrochromic device comprising: (a) a first electrode; (b) a second electrode; (c) an electrochromic material; and (d) a gel polymer electrolyte containing an ionic liquid. A method for manufacturing the same is also disclosed. The electrochromic device uses a gel polymer electrolyte comprising an ionic liquid. Therefore, there is no problem related with electrolyte leakage. Additionally, it is possible to manufacture electrochromic devices by using plastic materials, because the ionic liquid gel polymer electrolyte permits structural deformation with ease. Further, because the electrochromic device uses an ionic liquid, it is possible to minimize side reactions between constitutional elements of an electrochromic device and electrolyte.
