Abstract
Electrochromic devices, preparation methods for electrochromic devices, and applications of electrochromic devices. The electrochromic device includes a first conductive layer, a color-changing layer and a second conductive layer that are arranged in succession. At least one first electrode lead is connected on the first conductive layer. The first electrode lead passes through the color-changing layer and the second conductive layer. At least one second electrode lead is connected on the second conductive layer, and the second electrode lead passes through the color-changing layer and the first conductive layer. The electrochromic device can achieve the application of the electrochromic device under the premise that the two conductive layers are not staggered, and on the basis of implementing electrochromism. The technical effect of gradual color change can be achieved by changing the magnitude of the power supply voltage and/or current.
