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.

About the Speaker

Professor Santi Maensiri obtained his first degree in Physics at Khon Kaen University Thailand. He then received his M.Sc. (Ceramic Processing) from Leeds University, and D.Phil. (Materials Science) from the University of Oxford, UK. He has published more than 330 Scopus papers with citations over 10500 times and h-index of 53 in the areas related to applied physics, materials physics, materials science, and nanomaterials. He was appointed SUT’s Head of School of Physics, the Dean of Institute of Science, and later Vice Rector for Academic Affairs and Internationalization at Suranaree University of Technology (SUT), Thailand. He is currently the Dean of Institute of Science, the Director of Centre of Excellence in Advanced Functional Materials, and Director of NANOTEC-SUT Research Network on Nanotechnology for Nanomaterials and Advanced Characterizations. At the national level, he is presently serving as the President of the Materials Research Society of Thailand (MRS-Thailand, member of IUMRS). For his research strength, he has received numerous awards, such as the National Research Award in Physical Science and Mathematics from The National Research Council of Thailand (NRCT) for two consecutive years (2012 and 2013), the 2013 TRF Senior Research Scholar from the Thailand Research Fund (TRF), and National Outstanding Researcher Award in Physical Science and Mathematics (Physics) also from NRCT, to name a few.
