Research progress in spectrum regulation devices based on reversible metal electrodeposition

Abstract

Reversible metal electrodeposition device (RMED) is a new type of electrochromic device, which has excellent spectrum regulation ability in visible and infrared regions, and has unique advantages such as simple structure, low energy consumption, multi-color state regulation. It shows great application potential in intelligent window, thermal management, information display and other fields. In recent years, the performance of RMED has been improved through structural design and electrolyte composition optimization, but there are still some problems such as poor open circuit stability, short cycle life and limited size, which seriously hinder the development and application of RMED. From the perspectives of spectral tuning range and performance optimization, the research progress of spectrum regulation devices based on reversible metal electrodeposition was summarized in this article. The spectral tuning range mainly includes visible and infrared bands. The current development status of RMED in the visible light region using different metal deposition systems was briefly introduced, which is also the most widely studied direction at present. The electrode innovation for achieving infrared spectral tuning was the focus of the discussion. The research methods for improving device performance such as open-circuit stability and cycling stability were discussed. Finally, it was pointed out that RMED still faces some development difficulties, and in the future, in-depth and systematic research can be carried out on device performance and theoretical mechanism, among other aspects.
