摘要：
Amorphous WO3 has attracted significant attention in electrochromic material research owing to its distinct structure and exceptional electrochemical characteristics. This review provides a succinct overview of the structure of amorphous WO3, the factors influencing its formation, and the advantages and disadvantages of amorphous WO3 compared with crystalline WO3. The mechanisms and characteristics of recent optimization strategies, including elemental doping, composite materials, and high-valent electrolyte ion selection, are intended to improve the electrochromic performance of amorphous WO3. Furthermore, the promising applications of amorphous WO3 electrochromic thin films in smart windows, infrared shielding devices, visual supercapacitors, and flexible wearable devices are summarized. This review will inspire further research into the application of amorphous WO3 in electrochromic devices and provide a robust material foundation for future technological advancements.
