Description

technical field [0001] The invention belongs to the technical field of functional devices and electrochemical materials, and in particular relates to a method for preparing an all-solid-state electrochromic device. Background technique [0002] The so-called electrochromic (EC for short) refers to the phenomenon that the material undergoes a stable and reversible color change under the action of an external electric field. In terms of appearance performance, it is manifested as a reversible change in color and transparency. With the deepening of energy saving, environmental protection, and aesthetic concepts, Lampert et al. (Lampert C.M., Solar Energy Mater. & Solar Cells, 1994, 32: 307-321) proposed to apply electrochromic devices (ECD) to energy saving in buildings, vehicles, etc. Daylighting system, development of electrochromic windows (Smart Window). Using this kind of smart window can effectively control the solar radiation energy entering the building while obtaining...
