ELECTROCHROMIC DEVICE BASED ON TRANSPARENT METAL MESH ELECTRODE

WIPO Patent Application WO/2023/004973

A1

Provided is an electrochromic device based on a transparent metal mesh electrode, comprising a four-layer structure, namely a first layer, a second layer, a third layer and a fourth layer in sequence, wherein the first layer is transparent conductive glass, and the third layer is a zinc mesh or a galvanized metal mesh; the fourth layer is transparent non-conductive glass and is used for placing the third layer; and the second layer is a cavity and is used for accommodating an electrolyte. The electrolyte is a complex ion electrolyte generated by the complex reaction of a zinc salt or zinc oxide and a strong base; and the first layer and the third layer are connected with wires. According to the electrochromic device prepared in the present invention, the influence of ion polarization is reduced, a better deposition uniformity is obtained, the influence of the by-products Zn(OH)2 and ZnO on the reversibility of the device is reduced by the strong base electrolyte, and the electrochromic device has a good transmittance adjustment ability, better realization of electrochromism, and better application of the device.
