Role of Cations in Ionic Liquid-Based Polymer Composite Electrolyte Organic Supercapacitors.

ABSTRACT: Solid-state supercapacitors utilizing ionic liquid-based polymer composite electrolytes (IL-b-PCEs) have gained attention as promising candidates for next-generation energy storage systems due to their high ionic conductivity, wide electrochemical stability, and nonvolatility. However, the specific influence of cation species on the electrochemical performance of IL-b-PCEs has remained insufficiently explored. This study aims to analyze the impact of three distinct cations 1-ethyl-3-methylimidazolium (EMIM⁺), 1-butyl-3-methylimidazolium (BMIM⁺), and proton (H⁺), on the physicochemical characteristics and charge storage behavior in PVA-based IL-b-PCEs systems. The Fourier-transform infrared (FTIR) spectroscopy elucidates a notable shift
