Abstract
An electrochromic device and an electrochromic method therefor are disclosed. The electrochromic device comprises a first substrate, a first transparent conductive layer, a first electrochromic layer, an electrolyte layer, a second electrochromic layer, a second transparent conductive layer, and a second substrate which are sequentially stacked. Both the first electrochromic layer and the second electrochromic layer are made of a cathode electrochromic material or made of an anodic electrochromic material. The electrochromic method for the electrochromic device comprises: circularly applying a voltage having a direction opposite to and same as that of a first voltage to a pretreated electrochromic device. Because a structure in which two layers of electrochromic layers are made of the anodic electrochromic material or the cathode electrochromic material is used, and a specific electrochromic method is combined, the switching between different colors can be performed, and a selection range of the electrochromic materials can be expanded.
