Electrochromism Research in China

Electrochromism has been developed for more than 50 years since it was discovered in the 1960s.The optical properties, such as color, transmittance, reflectance and emissivity, of electrochromic materials can be changed reversibly under low applied voltages.Electrochromic materials have a wide range of regulatable spectrum, which can realize the broadband control from visible to mid far infrared.Electrochromic materials show a wide application prospect in the fields of intelligent window, display, anti-glare rearview mirror, intelligent thermal control and camouflage.In the past decade, electrochromism research has shown a trend of vigorous development, especially in China.Electrochromism is attracting researchers in the fields of nanomaterials, vacuum coating, lithium-ion batteries, supercapacitors, sensing and display to get involved in this interdisciplinary field, gradually becoming one of hot research topics.In the last special issue Electrochromic Materials and Devices (2021, 36(2)), we published 5 papers "Multi-functional Electrochromic Devices: Strategies Based on Multiple and Single Devices",
