Abstract
A flexible variable emissivity electrochromic device and a preparation method thereof are disclosed. The device includes a working electrode, a gel electrolyte layer, and a counter electrode sequentially from top to bottom. The working electrode includes a flexible polymer film and a metal film, the flexible polymer film is a surface-modified film and/or a film with a transition layer plated on a lower side thereof, and the metal film is deposited on the surface-modified film or the transition layer. The electrolyte layer includes a porous membrane and an electrolyte. The electrolyte is infiltrated in the porous membrane. The electrolyte includes an electrochromic material containing metal ions and a solvent, the metal ions enable reversible electrodeposition and dissolution, and metal of the metal ions is different from that used in the metal film. The preparation method includes preparing and assembling a working electrode, a gel electrolyte layer and a counter electrode.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
