Due to the growing demand for eco-friendly and sustainable energy storage systems, this study presents an analysis of ion transport in cassava starch (CS)- polyvinylpyrrolidone (PVP) nanocomposite polymer electrolytes for improved lithium-ion battery (LIB) applications. In this study, five electrolyte samples were produced using the direct-heat solution casting method. The data obtained from these samples were analyzed using SEM micrographs, and theoretical models including ionic conductivity equation, Nernst-Einstein equation, Fick’s law of diffusion, and Faraday’s law of electrolysis. The results showed that Sample 3, which contained equal amounts of CS and PVP, exhibited a smooth surface with minimal cracks and the highest ionic conductivity (1.74 ???? 10−3 ????⁄????????), diffusion coefficient (3.34 ???? 10−9 ????????2⁄????), diffusion flux (2.31 ???? 10−4 ????????????⁄????2 . ????), and electric charge (3.94 ???? 10−3 ????⁄????). The high ion transport properties observed in Sample 3 indicate excellent homogeneity between the components of the electrolyte film, making it ideal for enhanced lithium-ion battery applications.
