Biomass-derived activated carbon for high-performance energy storage devices

Biomass-derived activated carbon (BDAC) has emerged as a promising material because of its renewability and worldwide availability. This review explores the various production methods and evaluates activated carbon obtained from various biomasses, such as agricultural and plant wastes, emphasizing its potential use in supercapacitors. These activation processes incorporate both physical and chemical methods to enhance the surface area, optimize the pore size distribution, and improve electrical conductivity. The electrochemical performance of these materials as supercapacitor electrodes demonstrates their high capacitance, energy density, and cycle stability, making them suitable for advanced energy storage systems. These findings emphasize the potential of BDAC as an alternative to traditional carbon materials, leading to environmentally friendly energy systems. Furthermore, the use of renewable and abundant biomass sources corresponds to the objective of environmental sustainability by providing an eco-friendly and cost-effective alternative for the conservation of energy. This study emphasizes the potential of activated carbon derived from biomass to develop supercapacitor technologies for a more sustainable future.
