Varieties of natural biomass have been utilized to prepare porous carbon materials for supercapacitor applications. In this work, porous activated carbons derived from Pleurotus eryngii were prepared by carbonization and KOH activation. The activated carbons presented a large specific surface area of 3255 m 2 ·g −1 with high porosity. The as-prepared electrode exhibited a maximal specific capacitance of 236 F·g −1 measured in a three-electrode cell system. Furthermore, the assembled symmetric supercapacitor showed a specific capacitance of 195 F·g −1 at 0.2 A·g −1 and a superior specific capacitance retention of about 93% after 15000 cycles. The desirable capacitive behavior suggests that Pleurotus eryngii is an attractive biomass source of carbon materials for the potential supercapacitor applications.

“…The appearance of thiophene-S may contribute to the enhancement of conductivity of doped graphene. This indicates that a fraction of carbon atoms on graphene surface or edges are replaced by N and S heteroatoms, tailoring its electron properties and consequently tuning chemical performance [41]. In addition, the N and S heteroatoms structure increase the affinity of graphene to chemisorb the T-Nb 2 O 5 [35].…”

“…Most of biomass materials possess intriguing hollow tubular structure, such as cotton [73][74][75], dandelion [76], poplar catkins [77], willow catkins [78][79][80][81][82], which can be used as precursors to produce conductive carbon tubes. According to the literature, cotton fibers can still inherit hollow porous carbon tubes after carbonization and chemical activation (Fig.…”

Currently, carbon materials, such as graphene, carbon nanotubes, activated carbon, porous carbon, have been successfully applied in energy storage area by taking advantage of their structural and functional diversity. However, the development of advanced science and technology has spurred demands for green and sustainable energy storage materials. Biomass-derived carbon, as a type of electrode materials, has attracted much attention because of its structural diversities, adjustable physical/chemical properties, environmental friendliness and considerable economic value. Because the nature contributes the biomass with bizarre microstructures, the biomass-derived carbon materials also show naturally structural diversities, such as 0D spherical, 1D fibrous, 2D lamellar and 3D spatial structures. In this review, the structure design of biomass-derived carbon materials for energy storage is presented. The effects of structural diversity, porosity and surface heteroatom doping of biomass-derived carbon materials in supercapacitors, lithium-ion batteries and sodium-ion batteries are discussed in detail. In addition, the new trends and challenges in biomass-derived carbon materials have also been proposed for further rational design of biomass-derived carbon materials for energy storage.
