Abstract

The invention relates to a preparation method of a quasi-solid electrochromic device. The device consists of a first substrate, a first transparent conductive layer, an electrochromic layer, an ion transmission layer, an ion storage layer, a second transparent conductive layer and a second substrate sequentially. The preparation method comprises the following steps: (1) preparing the first functional substrate; (2) preparing the second functional substrate; (3) preparing the ion storage layer; (4) performing alignment heating and laminating; (5) removing bubbles by a high-pressure kettle; and (6) gluing frames. The preparation method of the quasi-solid electrochromic device has the advantages of simple method, low investment cost, high quality controllability of finished products, and high color-changing uniformity, and can realize large-area industrialized production.

Description

technical field [0001] The invention belongs to the field of electrochromic devices, in particular to a quasi-solid-state electrochromic [0002] Device fabrication method. Background technique [0003] Electrochromism refers to the phenomenon that optical properties (reflectivity, transmittance, absorptivity, etc.) undergo a stable and reversible color change under the action of an applied electric field. Electrochromic technology has been developed for more than 40 years. Electrochromic devices (Electrochromic Device, ECD) are widely used in smart windows, It has broad application prospects in fields such as displays, spacecraft temperature control and modulation, automotive non-glare rearview mirrors, and weapons and equipment stealth. [0004] Electrochromic devices generally have a five-layer structure: a transparent conductive electrode layer, an electrochromic material layer, an electrolyte layer, an ion storage layer, and another conductive electrode layer. At pre...
