Abstract
An EC element includes a separator that divides the gap between electrodes into two sections, and a pair of EC layers with the separator therebetween. The separator has an ionic resistance of 50 Ωcm2 to 300 Ωcm2 in the thickness direction thereof when impregnated with 0.1 M tetrabutylammonium TFSI/propylene carbonate solution.
Claims11
An electrochromic element comprising:
- a first electrode;
- a second electrode;
- a separator that divides a gap between the first electrode and the second electrode into two sections;
- a first electrochromic layer disposed between the first electrode and the separator and containing at least one cathodic electrochromic compound;
- and
- a second electrochromic layer disposed between the second electrode and the separator and containing at least one anodic electrochromic compound, wherein the separator has an ionic resistance of 50 Ωcm2 to 300 Ωcm2 in the thickness direction thereof when impregnated with 0.1 M tetrabutylammonium bis(trifluoromethanesulfonyl)imide/propylene carbonate solution.
