A Comprehensive Review of the Functionalized Integrated Application of Gel Polymer Electrolytes in Electrochromic Devices

With the global push for energy conservation and the rapid development of low-power, flexible and wearable optical displays, the demand for electrochromic technology has surged. Gel polymer electrolytes (GPEs), a crucial component of electrochromic devices (ECDs), show great promise in applications. This is attributed to their efficient ion-transport capabilities, excellent mechanical properties and strong adhesion. All of these characteristics are conducive to enhancing the safety of the devices, streamlining the packaging process, significantly improving the electrochromic performance of ECDs and boosting their commercial application potential. This review provides a comprehensive overview of GPEs for ECDs,…
