Abstract
Provided is a smart electrochromic device. The smart electrochromic device may comprise: first and second electrodes disposed facing each other; an electrochromic layer disposed between the first and second electrodes and containing a metal oxide; and an electrolyte which is disposed between the second electrode and the electrochromic layer and which contains a mixture of a first base electrolyte containing silver (Ag), a second base electrolyte containing lithium (Li), and a solvent.
Claims8
A smart electrochromic device comprising:
- a first electrode and a second electrode disposed facing each other;
- an electrochromic layer disposed between the first electrode and the second electrode, the electrochromic layer containing a metal oxide;
- and
- an electrolyte disposed between the second electrode and the electrochromic layer, the electrolyte containing silver (Ag), lithium (Li), and a solvent, and wherein the electrolyte includes bis(trifluoromethanesulfonyl)imide (TFSI) ions as counter ions for the Li,
- wherein a molar ratio of the Ag to the Li is greater than 1:5 and less than 1:20, and
- wherein transmittance and reflectance for visible light wavelengths and transmittance and reflectance for near-infrared ray wavelengths are capable of being selectively controlled according to movements of at least one of silver ions or lithium ions in the electrolyte.
