ABSTRACT: The development of an electrolyte system using a biopolymer composite with pectin and an ionic salt (KI) is revealed in this communication. The solution cast method has been used to create composite electrolyte films of pectin biopolymer that has been produced with KI salt at different concentrations. The conductivity for pectin biopolymer-based electrolyte sheets can reach orders of 7.8×10-6 S/cm, a three-order increase above the conductivity of pure pectin (2.7 x10-9 S/cm). The current communication describes electrical, structural, and optical analyses of the biopolymer electrolyte films. The electrical conductivity of the produced biopolymer electrolyte sheets is demonstrated by the Nyquist plot. The optical characteristics are represented by the POM images, which emphasize the amorphous nature of the electrolyte layers. The greatest cationic transference number reveals the ionic composition of biopolymer electrolyte sheets. The optical properties were investigated using UV-visible optical absorption spectroscopy in the 300–800 nm wavelength range.
