Electrochromic devices (ECDs) can reversibly regulate their optical properties (transmittance, reflectance, and color) via internal ion migration under applied voltage, thus exhibiting advantages such as controllable switching, high contrast ratio between bleached and colored states, and low power consumption. Based on these features, ECDs have been studied in the fields of photothermal modulation, dynamic display, energy storage, and camouflage. Recently, remarkable breakthroughs have been made in ECDs with respect to the contrast ratio, coloration efficiency, cycle stability, and scale-up fabrication. Nevertheless, the response speed, which is related to the efficiency and power consumption of devices, especially in application scenarios with strict requirements on switching rate, remains a major restricting parameter.

基于快速开关 WO3 的电致变色器件：设计、制造和应用

电致变色器件 (ECD) 可以通过施加电压下的内部离子迁移来可逆地调节其光学特性（透射率、反射率和颜色），因此具有可控切换、漂白和着色状态之间的高对比度以及低功耗等优势。基于这些特性，ECD在光热调制、动态显示、能量存储和伪装等领域得到了研究。最近，ECD 在对比度、显色效率、循环稳定性和放大制造方面取得了显着突破。然而，与器件效率和功耗相关的响应速度，尤其是在对开关速率有严格要求的应用场景中，仍然是一个主要的制约参数。
