Highly conductive biocarbon nanostructures from burlap waste as sustainable additives for supercapacitor electrodes

“…Electrical conductivity of biocarbon materials mainly depends on their graphitic nature, which is influenced by many factors such as the properties of feedstock and pyrolysis temperature. 3 Pyrolysis is a thermochemical process in which organic materials are subjected to high temperature treatment in the absence of oxygen. Specifically, in the context of biocarbons, the precursors, which may include biomass or organic waste materials, undergo a series of complex decomposition reactions during pyrolysis which involve dehydration, depolymerization, and the generation of volatile compounds, ultimately resulting in the formation of biocarbons.…”
