Executive Summary : | Supercapacitors are nowadays thought of as essential and complementing devices for modern-day batteries. Supercapacitors show high power density in comparison to batteries and can be employed in applications demanding high power along with the high energy density of the batteries. The research on integrated supercapacitor and battery systems is gaining more and more significance as they promise a new sustainable source of green energy as an alternative to conventional nonrenewable resources of energy. Supercapacitors are also gaining incredible importance in the applications such as computers and memory storage devices. The present study can play a vital role in enhancing the power density and the energy density of the supercapacitors fabricated using RuO2/LiCuMn ferrite nanocomposites. The nanocomposite is expected to combine the high electrochemical properties of RuO2 with the unique electrical behavior of LiCuMn ferrite resulting in a hybrid material highly suitable for supercapacitor electrodes. The proposed study includes the synthesis of RuO₂ followed by RuO₂/LiCuMn ferrite nanocomposites using the hydrothermal method of synthesis. The RuO2/LiCuMn ferrite nanocomposites with varying compositions of RuO2, Li, Mn, and Cu will be investigated for their structural, electrical, magnetic, and optical properties using various characterization techniques such as X-ray diffraction (XRD), Transmission electron microscopy (TEM), Scanning electron microscopy (SEM), Energy dispersive spectroscopy (EDS), Impedance spectroscopy, Fourier transforms Infra-Red spectroscopy (FTIR), Raman spectroscopy, Vibrating sample magnetometer etc. The electrochemical performance of these nanocomposites will be investigated using an electrochemical workstation. The study also involves the fabrication of a prototype supercapacitor using RuO2/LiCuMn ferrite nanocomposites. |
