Gel polymer electrolyte containing ionic liquid and electrochromic device using the same
First Claim
1. A method for manufacturing an electrochromic device, which comprises the steps of:
- (a) providing a first electrode and a second electrode;
(b) injecting an electrolyte precursor solution into the gap between the first electrode and the second electrode through an inlet and sealing the inlet, wherein the electrolyte precursor solution comprises (i) an ionic liquid, (ii) a monomer operable for forming a gel polymer by polymerization, and (iii) a polymerization initiator, and wherein the electrolyte precursor has a mixing ratio on the weight basis of 0.5-0.95;
0.05-0.5;
0.00-0.05, when, x represents ionic liquid, y represents monomer operable for forming a gel polymer by polymerization, and z represents polymerization initiator, with the provision that x+y+z=1; and
(c) polymerizing the electrolyte precursor solution to form an ionic liquid gel polymer electrolyte.

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.
