“…Carbonaceous materials such as activated carbons (ACs), carbon aerogels, carbon nanotubes (CNTs), carbide-derived carbons, graphene, and others have been widely used as electrode materials in supercapacitors because they are cost-effective, have excellent electrical conductivity, and are widely available. − In electrochemical double-layer capacitors (EDLCs), ACs are often employed as electrode materials because of their large surface area and tunable porosity . Carbon materials derived from biomass are always preferable for most applications, including gas adsorption, , wastewater treatment, , anode material in batteries, , and so on, because they are less expensive, more easily accessible, and have the least environmental impact. Biomass-derived activated carbons are gaining traction as an active electrode material for supercapacitors due to their remarkably good pore structure, ease of synthesis, high specific surface area, and high conductivity …”
