The reversible metal electrodeposition device (RMED) is a novel electrochromic application that utilizes the appearance and disappearance of a metal layer to achieve spectrum control. A thin metal film with a thickness of a few tens of nanometers would be highly reflective in the visible and infrared region, making it an ideal material to achieve light and heat modulation. Because of their outstanding spectrum control ability, RMEDs can be applied to displays, smart windows, and thermal camouflage. However, as is the case with many other electrochromic devices, difficulties in device enlargement pose significant challenges to the application of RMEDs. Herein, an overview of the milestone advances of RMEDs is provided, with a focus on their application as smart windows, which is the most extensively studied topic. Recent attempts to improve their openācircuit stability and designs for device enlargement are highlighted. Finally, insight into the remaining challenges and future prospects in this field is provided.
