With the popularity of wearable electronic devices, flexible electronic devices have become a hot topic of current research. Flexible electrochromic devices are characterized by green environmental protection, low cost, large area, adaptability and convenient production and transportation. They are not only used in intelligent windows of green buildings, dimming glass of electric vehicles, military camouflage, infrared radiation control and variable color short circuit warning batteries, but also have great application prospects in medical care and equipment, and are considered as the key technology of wearable energy storage devices and smart textiles in the future. Based on the flexible electrochromic structure, the development of functional layers such as flexible substrates, electrode materials, electrochromic materials and electrolyte materials was discussed. The relationship between device materials and structure was described clearly, and the key of performance promotion was found. Moreover, several personal insights on the existing challenges and future research direction of flexible electronic devices were considered based on current progress.
