Abstract

See full text

Disclosed are an electrochromic element, device, and product, and a manufacturing method therefor. The electrochromic device (7) comprises: an electrochromic yarn (6), an ion storage yarn (18), and a power source (8), wherein the electrochromic yarn (6) contains a first flexible conductive yarn (5) and an electrochromic layer (4) coated on a surface layer of the first flexible conductive yarn (5); the ion storage yarn (18) contains a second flexible conductive yarn (1) and an ion storage layer (17) coated on a surface layer of the second flexible conductive yarn (1); and the first flexible conductive yarn (5) is electrically connected to a negative electrode of the power source (8), and the second flexible conductive yarn (1) is electrically connected to a positive electrode of the power source (8). The electrochromic device (7) can achieve a clear color development effect and make an electrochromic material have a good fastness. The preparation method is simple to operate and easily realizes industrial batch production.
