Ink for electrochromic device and electrochromic device and method of manufacturing the same

摘要

Disclosed is ink for an electrochromic device including an electrochromic material, a metal salt, and a solvent. Disclosed also is an electrochromic device that includes a first electrode and a second electrode facing each other, an auxiliary electrode disposed on the first electrode or the second electrode, an electrochromic layer applied on the auxiliary electrode, and an electrolyte interposed between the first electrode and second electrode, wherein the electrochromic layer is formed using ink including an electrochromic material and a metal salt. Disclosed also is a method of manufacturing the electrochromic device.
