SOLID STATE SUPERCAPACITORS BASED ON rGO/RuO¿ COMPOSITE thin FILMS: Chemically synthesized films for supercapacitor application

Bol

This thesis focuses on the synthesis, characterization, and electrochemical performance of ruthenium dioxide (RuO¿) thin films prepared using the Successive Ionic Layer Adsorption and Reaction (SILAR) method. RuO¿ is a promising electrode material for supercapacitor applications due to its high electrical conductivity, excellent redox activity, and superior specific capacitance. The SILAR technique offers advantages such as low cost, simplicity, room-temperature processing, and precise control over film thickness. Structural, morphological, optical, and electrochemical characterizations were carried out using XRD, XPS, FT-IR, RAMAN, SEM, cyclic voltammetry, and electrochemical impedance spectroscopy. The results demonstrate that SILAR and CBD deposited RuO¿ thin films exhibit enhanced electrochemical performance, making them suitable for next-generation energy storage devices.
