摘要

PMMA stands out as a highly valuable polymer electrolyte with extensive interdisciplinary applications, offering benefits, such as high energy efficiency and excellent environmental adaptability. However, its limited mechanical properties hinder its commercial use. In this study, SN-doped PMMA composite electrolytes with varying PMMA:SN ratios (9:1, 7.5:2.5, and 6:4) were fabricated using the solution casting technique. The findings revealed that the PMMA/SN = 7.5:2.5 electrolyte exhibited the best performance in terms of response time and cycling stability. Cyclic voltammetry (CV) analysis indicated that the lithium ion diffusion coefficient for the PMMA/SN = 7.5:2.5 electrolyte reached an optimal value of 5.2 × 10–10 cm2/s. The improvement in electrolyte performance is primarily attributed to the nitrile group in SN, which creates an additional conductive pathway for lithium ion transport. This enhances the mobility of lithium ions within the electrolyte layer, thereby increasing ionic conductivity and further boosting the performance of electrochromic devices. This research offers a viable approach to enhancing the functionality of electrochromic devices.
