“…Meanwhile, the rich pores in tubular carbon walls further increase the specific surface area for ions storage, as well as provide fast ions transport channels. Some biomass, such as enteromorpha prolifera, 47 cotton, 93 kapok fibers, 217,218 and coconut fibers, 53 possesses natural hollow tubular structure that can easily be converted into hollow tubular BDCs. For instance, BDCs from kapok fibers have tubular structures and N‐containing sandwich‐like walls, promoting ions transport.…”

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.

“…Theoretically, almost all natural biomass can be carbonized into carbon with unique structures and natural porosity; however, only natural fibers with well-organized structures lead to PCFs. These fibers include cotton, 110,128–132 sisal, 133 jute, 134 silk, 135 bamboo, 136 fungi, 137 collagen, 109,138 and bacterial cellulose. 139 For example, Yang et al produced activated PCFs with a large amount of surface defects through the carbonization of cotton fibers followed by activation with KOH.…”

“…As the handling expense of environmental waste increases, the recycling of bio-waste or conversion to the useful products is very important to protect the environment [11]. As is known, biomass wastes contain abundant carbohydrates such as cellulose and lignin, which have a great potential to prepare activated carbon with a very low cost [12]. Studies have shown that biomass-derived carbon can have a porous structure and a large surface area, provides an active site for enhancing ion migration between electrolyte and carbon and has excellent electrochemical properties [10,[12][13][14].…”

It is very important to transform biomass-derived waste into useful materials with high performance. In this report, the N, O, P multiple heteroatom-doped activated porous carbon materials with enhanced electrochemical performance are prepared using durian shell-derived hydrochar. The as-prepared activated carbon materials show a characteristic of moderate specific surface area, micropore-dominant pore structure and multiple heteroatoms doping. As electrode in supercapacitor, the as-prepared N, O, P-doped porous carbon material can deliver a specific capacity of 184 F g-1 at a current density of 0.5 A g-1 in 1 M H 2 SO 4 aqueous solution and shows excellent cycle stability with a retention rate of *88% after 10000 cycles. In addition, in the redox electrolyte of H 2 SO 4 and KI aqueous solution, N, O, P co-doped activated porous carbon can provide a capacitance of * 560 F g-1 at 2 A g-1 (corresponding to energy density of 12.4 Wh kg-1 at a power density of 318 W kg-1). This work provides a novel way to enhance the electrochemical performance of the biomass waste-derived carbon, helping to further boosting their application in energy storage field.
