Electrochromism Research in China

Electrochromism has a history of more than 50 years since it was discovered in the 1960s. An electrochromic material is a material whose color can undergo reversible change under an external electric field. Electrochromic materials have a wide adjustable spectral range, which can realize wide-band control from visible to mid- and far-infrared. It has broad application prospects in the fields of smart windows, displays, anti-glare rearview mirrors, smart thermal control and camouflage. In the past ten years, electrochromic research has shown a trend of vigorous development, especially in China. Electrochromic has attracted researchers in the fields of nanomaterials, vacuum coating, lithium-ion batteries, supercapacitors, sensing, and displays to get involved in this intersection. The subject area has gradually become one of the research hotspots.
