A self-powered electrochromic device (ECD) powered by a self-rechargeable battery is easily fabricated to achieve electrochromic window design, quantitative reactive oxygen species (ROS) sensing, and energy storage. The special design of the battery was composed of Prussian blue (PB) and magnesium metal as the cathode and anode, respectively, which exhibits fast self-charging and high power-density output for continuous and stable energy supply. Benefitting from the fast electrochromic response of PB, it was not only used for structuring self-rechargeable batteries but also used as an electrochromic display for highly sensitive self-powered ROS sensing and visual analysis. We believe that this work provides a solution to self-powered ECDs limited to a single application and could combine the applications in smart windows, ROS sensing, and other fields together, and in the meantime provide a solution for energy supply problems.
一种由自充电电池供电的自供电电致变色器件（ECD）很容易制造出来，以实现电致变色窗口设计、定量活性氧（ROS）传感和能量存储。该电池的特殊设计分别由普鲁士蓝（PB）和镁金属作为阴极和阳极组成，它具有快速自充电和高功率密度输出的特点，可实现持续稳定的能量供应。受益于PB快速的电致变色响应，它不仅用于构建自充电电池，还用作电致变色显示器，用于高灵敏度的自供电ROS传感和视觉分析。我们相信这项工作为限于单一应用的自供电ECD提供了解决方案，能够将智能窗户、ROS传感等领域的应用结合在一起，同时也为能量供应问题提供了解决方案。
