Flexible solid-state supercapacitors are gaining popularity due to their advantages, including flexibility, lightweight design, high power density, rapid charge and discharge rates, broad operating temperature ranges, long cycle life, safety, and ease of fabrication. The use of gel polymer electrolytes enhances ionic conductivity while addressing safety concerns associated with liquid electrolytes.
This research focuses on developing nanocomposite electrodes using Ag-decorated zinc oxide, synthesized through a chemical deposition method on carbon paper, and ferrite applied via a drop-casting technique. The goal is to create electrodes that can operate across a wide voltage range in a non-aqueous electrolyte.
Advanced characterization techniques, such as atomic force microscopy, X-ray diffraction, field emission scanning electron microscopy, and Raman spectroscopy, are employed to analyze the structural properties of the electrodes. The findings reveal an effective specific capacitance of approximately 70 milliFarads per square centimeter.
