Title:
MULTI-METAL ANODE SELF-POWERED-MULTI-MODAL ELECTROCHROMIC DEVICE AND PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/221288
Kind Code:
A1
Abstract:
A multi-metal anode self-powered-multi-modal electrochromic device and a preparation method. The preparation method comprises: cleaning and airing a first conductive substrate (1) and a second conductive substrate (6); growing a dual-band electrochromic material on the second conductive substrate (6) by means of methods of, including but not limited to, spin coating, hydrothermal or magnetron sputtering; making metal A and metal B adhere to two edges of one side of the first conductive substrate (1); and taking the second conductive substrate (6) loaded with the dual-band electrochromic material as a working electrode, taking the first conductive substrate (1) having the metal A and the metal B as a metal anode, and finally injecting an electrolyte (4) and packaging same into a device. A thin film cathode material is combined with different metal anodes to generate open-circuit voltages of different magnitudes, and, by means of the built-in voltage, multiple modes can be realized to dynamically modulate the degree of transmission of visible light and near-infrared light.
