AbstractElectrochromic materials (ECMs) have important potential applications in the field of intelligent optoelectronic displays. However, ECMs and its devices cannot be truly applied on a large scale until the problem of their long‐period performance degradation is really solved. This paper focuses on summarizing the attenuation mechanism of common ECMs, which is mainly divided into three types: structural damage, irreversible reaction and ion capture, and summarizes four optimization strategies for the cyclic stability of electrochromic materials at the present stage: doping is used to change the internal structure of the material in order to achieve the purpose of improving the cyclic stability; composite means to allow a variety of materials to interact with each other in order to get the original material has no excellent performance; improve the cyclic stability of electrochromic materials by the special characteristics of nanostructures; and enhance the performance by optimizing the preparation process and regulating the parameters in the preparation process. Finally, the paper discusses the potential for optimizing the long‐term stability of ECMs in the future, based on the above research.This article is protected by copyright. All rights reserved.
