摘要

This work describes the fabrication of a nanocomposite polymer electrolyte system incorporating sodium iodide (NaI) with poly (ethyl methacrylate) (PEMA) and carbon black as a nanofiller, for its astounding electrochemical capabilities and environmental resilience. The solid polymer electrolyte was synthesized via solution casting method, and its characteristics were thoroughly investigated using a variety of analytical techniques. The electrical characterization indicates that the addition of the carbon black nanofiller markedly improves enhances conductivity, achieving a peak value of \(1.25 \times {10}^{-5}\) 1.25 × 10 - 5 S/cm at an optimal nanofiller conc. Of 8 wt.%, measurements of the ionic transference number affirm both ionic and electronic characters of the conductivity. Additionally, the nanocomposite demonstrates a substantial electrochemical stability window of \(3.78\) 3.78 V. Fourier transform infrared (FTIR) spectroscopy reveals significant interaction indicatives of good complexation, further substantiated reduce in crystallinity assessments conducted through polarized optical microscopy (POM). Synthesized carbon black dispersed polymer electrolyte with the highest conduction employed in dual energy storage devices.
