Abstract

The invention discloses an all-solid-state electrochromic device taking lithium aluminum silicate as an electrolyte layer and a preparation method of the all-solid-state electrochromic device, and relates to an electrochromic device and a preparation method thereof. The invention aims to solve the problems that the fading response speed of an existing all-solid-state electrochromic device is low,the transmittance modulation range of the device is small and the preparation cost is high. According to the method, the all-solid-state electrochromic device with the lithium aluminum silicate as theelectrolyte layer is composed of a substrate, a lower transparent conductive layer, an ion storage layer, a lower protective layer, the electrolyte layer, an upper protective layer, an electrochromiclayer and an upper transparent conductive layer which are sequentially arranged from bottom to top. The method comprises the steps: 1, depositing the lower transparent conductive layer, the ion storage layer and the lower protective layer by adopting a magnetron sputtering method; 2, depositing the electrolyte layer by adopting a magnetron sputtering method; and 3, depositing the upper protectivelayer, the electrochromic layer and the upper transparent conductive layer by adopting a magnetron sputtering method. According to the invention, the all-solid-state electrochromic device taking lithium aluminum silicate as the electrolyte layer can be obtained.

Description

technical field

[0001] The invention relates to an electrochromic device and a preparation method thereof. Background technique

[0002] Electrochromism is a phenomenon in which the optical properties of materials (reflectivity, transmittance, absorptivity, etc.) undergo stable and reversible color changes under the action of small electrical signals. The material with electrochromic phenomenon is called electrochromic material.

[0003] Electrochromic materials can be divided into inorganic electrochromic materials and organic electrochromic materials according to material types, and inorganic electrochromic materials include transition metals such as tungsten oxide, molybdenum oxide, vanadium oxide, titanium oxide, niobium oxide, and nickel oxide. Oxide and Prussian blue systems, organic electrochromic materials include polyaniline, polythiophene, viologen and other materials. Electrochromic devices made of electrochromic materials have been widely used in the fields of ...
