The activated carbon prepared at 725 C has shown a high specific capacitance of 521.65 Fg −1 at a current density of 0.5 A g and also achieved an energy density of 17.04 W h kg at a power density of 242.50 W kg −1 in the 6 M KOH electrolyte.

Bio wastes of diverse nature are studied to determine their potential as a valuable source in producing activated carbon. • Biomass-derived electrodes for

Activated carbon fibers (ACFs) are one of the most promising forms of carbonaceous nanoporous materials. They are most widely used as electrodes in different energy storing devices including batteries, capacitors, and supercapacitors. They are also used in gas diffusion layers, for electrocatalyst support and in bipolar plates of fuel cells.

Activated carbon has been widely explored for different application including, water pollution treatment (Nieto-delgado et al., 2019), gas capture (Li and Xiao, 2019), energy storage (Mensah-darkwa et al., 2019).

Porous carbons have several advantageous properties with respect to their use in energy applications that require constrained space such as in electrode materials for

Bio-mass derived activated carbon cathodes are designed for the safe and sustainable supercapacitors and aqueous Zn-ion capacitors. These cathodes have ultrahigh surface area, well-tuned pore structure and high heteroatom content that facilitate Zn 2+ ion diffusion and enhanced electrochemical performance.

Abstract. The production of activated carbon (AC) from lignocellulosic biomass through chemical activation is gaining global attention due to its scalability, economic viability, and environmental advantages. Chemical activation offers several benefits, including energy efficiency, reduced carbonization time, and lower temperature

The impregnated samples were activated at different temperatures (500 C to 800 C) and activated carbons were used to fabricate electrodes for energy storage. The results revealed that increasing activation temperature and K 2 CO 3 tailored the surface area (489–884 m 2 /g), morphological, and topography of the activated carbon to

Anthracite-based activated carbon stood out with a specific capacitance of 433 Fg ─1, demonstrating excellent energy storage potential. In wastewater treatment,

Activated carbon mainly relies on EDLC to achieve energy conversion, which is a process that depends on the electrostatic adsorption or desorption of ions in
