Abstract

Innovation in solid polymer electrolytes (SPEs) has paved the way for safer liquid electrolyte alternatives. The goal of this research is to improve ion conductivity by introducing fly ash variations into the SPE matrix. Corn starch, lanthanum nitrate ((La(NO)3)3) salt, and fly ash were used as fillers in the synthesis. Surprisingly, the solution casting procedure was successful in producing the SPEs for this study. X-Ray Diffraction (XRD) results indicated fascinating alterations within the SPE structure, which displayed a shift towards a more amorphous nature following the addition of fly ash. Fourier Transform Infrared Spectroscopy (FTIR) analysis revealed minor functional group alterations, notably in the C-OH groups, indicating interactions with fly ash. Scanning Electron Microscope (SEM) revealed fascinating interactions between fly ash and the SPE surface, leading in an enhanced presence of pores. Differential Scanning Calorimetry (DSC) revealed an impressive melting point graph for the greatest fly ash concentration, demonstrating that fly ash has a considerable influence. The addition of fly ash resulted in a significant increase in ionic conductivity, with the greatest conductivity reported at a 7% fly ash concentration, reaching an astonishing 8.60x 10^(-5) S/cm. These results show that the polymer and fly ash have a favorable ion interaction. As a result, corn starch based SPEs with fly ash filler have enormous potential for use as solid electrolytes in electrochemical devices. This study not only provides a safer alternative to liquid electrolytes, but it also advances ion-conducting materials, opening up new pathways for sustainable and efficient electrochemical technology.
