Carbon-based and Nanostructured Materials for Energy Storage Applications

Abstract: With the rapid increase in energy demand, energy storage devices with high power and energy densities, long cycle life, and environmentally friendly have emerged as potential candidates for current and next-generation technologies. In supercapacitors, the energy storage performance is largely determined by the structural and electrochemical properties of electrode materials. Consequently, numerous studies have focused on the developing electrode materials for achieving high-performance supercapacitors. In this work, we report the development of electrode materials consisting of biomass-derived porous carbon materials, nanostructured oxides and composites, and glass-based ceramic materials. The nanostructured materials and composites are prepared through various synthetic methods including sol-gel, hydrothermal, electrospinning, and so on. The physical characteristics of the materials are deliberated and discussed in detail using basic and synchrotron-based characterization techniques. The electrochemical performances of the materials are evaluated in aqueous-based electrolytes via electrochemical techniques consisting of cyclic voltammetry (CV), galvanostatic charge/discharge (GCD), and electrochemical impedance spectroscopy (EIS). Lastly, a simple fabrication of energy storage devices using the developed electrode materials as cathode/anode is demonstrated for energy storage applications.
