This research uses SnO₂ powder as the anode and NaFePO₄ powder was synthesized using the sol-gel method as the cathode, combined with binchotan carbon, PANi, and DMSO solvent, stirred until forming a paste, which was then coated and dried to form a thin sheet. NaNO₃ salt was used as the electrolyte with varying concentrations, while DMSO and H₂O. The results of characterization using SE…
