Abstract

The invention relates to an improved electrochromic device. The improved electrochromic device is characterized in that the edge of the substrate bonds a metal electrode used for connecting a transparent conductive layer or conductive reflecting layer in the electrochromic device with positive and negative anodes of an external power source, and can be applied to intelligent allochroic mirrors, allochroic windows and other fields. The improved electrochromic device has the advantages that the reflecting area or transmission area of the electrochromic device can be enlarged, the use of insoluble particles in seal gum can be reduced or omitted, and the influence of the insoluble particles on the properties of the electrochromic device is reduced.

Description

technical field [0001] The invention relates to the field of electrochromism, in particular to a connection mode between an electrochromic device and a driving power supply. Background technique [0002] Electrochromism refers to the reversible change of color of electrochromic materials under external driving power. It has great application value in electrochromic windows, automobile rearview mirrors, electrochromic glasses, high-resolution photoelectric camera equipment, photoelectric chemical energy conversion / storage, military camouflage and decorative materials, etc. [0003] as attached figure 1 As shown, the basic structure of the electrochromic device is similar to a sandwich, and the electrochromic layer is placed between two substrates deposited with conductive layers. In order to realize the control of the reflectivity or transmittance of the electrochromic device by the external driving power supply, the external power supply is mainly connected to the electrod...
