“…Heteroatoms doping by elements, such as O, N, S, P, and F, can enhance the electrical conductivity, change the surface wettability, introduce pseudocapacitance, accelerate the charge transfer, and facilitate the electrode/electrolyte interface reactions in BDCs 46,69,73,76,155 . The incorporation of heteroatoms within BDCs usually alters the electron‐accepting or donating characteristics, as well as the structures, thereby influencing the electrochemical performances.…”

Biomass is rich, renewable, sustainable, and green resources, thereby excellent raw material for the fabrication of carbon materials. The diversity in structure and morphology of biomass are relevant in obtaining carbon materials with different structures and performances. The inherent ordered porous structure of biomass also benefits the activation process to yield porous carbons with ultrahigh specific surface area and pore volume. Besides, obtained biomass‐derived carbons (BDCs) are hard carbon with porous morphology, stable structure, superior hardness/strength, and good cycling performances when used in electrochemical capacitors (ECs). The inherent N, S, P, and O elements in biomass yield naturally self‐doped N, S, P, and O BDCs with unique intrinsic structures. In this paper, the synthesis approaches and applications of BDCs in ECs are reviewed. It shows that BDCs electrochemical performances are highly determined by their pore structures, specific surface areas, heteroatoms doping, graphitization degree, defects, and morphologies. The electrochemical performances of BDCs can further be improved by compositing with other materials, such as graphene, carbon nanofibers/nanotubes, transition metal oxides or hydroxides, and conducting polymers. The future challenges and outlooks of BDCs are also provided.

“…AAWHC possesses a higher mesopore content (0.3962 mL g −1 ) than that of AWHC (0.1127 mL g −1 ) and WHC (0.0856 mL g −1 ), which means the pore size distribution of AAWHC is more reasonable. When used as electrode materials, sufficient micropores and mesopores as well as high SSA can provide sufficient electrolyte ion transmission channels and active sites for electrochemical reactions, further accelerating electrode efficiency [ 52 , 53 , 54 ].…”

Carbon materials have been widely used as electrode materials for supercapacitors, while the current carbon precursors are mainly derived from fossil fuels. Biomass-derived carbon materials have become new and effective materials for electrodes of supercapacitors due to their sustainability, low pollution potential, and abundant reserves. Herein, we present a new biomass carbon material derived from water hyacinth by a novel activation method (combination of KOH and HNO3 activation). According to the electrochemical measurements, the material presents an ultrahigh capacitance of 374 F g−1 (the current density is 1 A g−1). Furthermore, the material demonstrates excellent rate performance (105 F g−1 at a higher density of 20 A g−1) and ideal cycling stability (87.3% capacity retention after 5000 times charge–discharge at 2 A g−1). When used for a symmetrical supercapacitor device, the material also shows a relatively high capacity of 330 F g−1 at 1 A g−1 (a two-electrode system). All measurements suggest the material is an effective and noteworthy material for the electrodes of supercapacitors.

“…In some instances, the plant-derived materials served as alternatives to the traditional reagents to make the preparation (nanomaterials) procedure become a greener route. [38][39][40] These routes are referred to as Plant-Mediated Synthesis (PMS). The important reason to synthesize pure HAp without using toxic capping agents has to do with the biomedical applications of HAp for drug delivery, 41,42 antimicrobial purposes, 43 antiviral applications, 44 gene vector applications, 45 and in vitro cell viability studies, 46,47 all of which require nanomaterials of very high purity and very low toxicity (good bio compatibility).…”
