Abstract
The rapid depletion of fossil resources, coupled with growing environmental concerns, underscores the urgent need for renewable materials in energy storage systems. This study presents the fabrication of highly porous biocarbon materials derived from food waste via hydrothermal carbonization (HTC) for use as high-performance electrode materials in supercapacitors. The engineered biocarbons are thoroughly characterized using advanced analytical techniques, including scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) surface area analysis, thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS), Fourier-transform infrared (FTIR) spectroscopy, and Raman spectroscopy, to investigate their morphological, structural, and physicochemical properties. The electrochemical performance of the biocarbon electrodes is evaluated through cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS) to assess their charge storage capabilities. Furthermore, life cycle assessment (LCA) and techno-economic analysis (TEA) are conducted to evaluate the environmental sustainability and commercial feasibility of the developed biocarbon materials. This research highlights the significant potential of food waste-derived biocarbons as sustainable and cost-effective electrode materials for energy storage applications, contributing to both environmental sustainability and the advancement of clean energy technologies.
