“…Moreover, the biomass-derived carbon materials with abundant micropores can also be prepared from ginkgo leaves [101], cotton stalk [102], pine needles [103], acacia gum [104], pomelo peel [105] popcorn [106], cornstalk [107], walnut shell [108]. Furthermore, microporous surface area and pore volume depend on the amount of KOH and heat treatment temperature [42,102,104]. As the ratio of alkali/carbon varies from 1:1 to 6:1, the SSA and micropore volume of the carbon materials also increase [5,102].…”

“…Furthermore, microporous surface area and pore volume depend on the amount of KOH and heat treatment temperature [42,102,104]. As the ratio of alkali/carbon varies from 1:1 to 6:1, the SSA and micropore volume of the carbon materials also increase [5,102]. With the increasing temperature, the SSA and pore volume of the carbon material also show a peak at a certain temperature [42] due to the collapse of the micropores at higher temperature [97,103].…”

“…All the characteristics strongly suggest that biomass-derived carbon could be qualified for the electrode of supercapacitors. To date, various biomass-derived carbon materials with high SSA, abundant pore structure and modified functional groups have been prepared, such as the stems [87,102,157,[177][178][179], leaves [34,90,101,103,126], seeds [48,77,79,154], fructus [180][181][182], pericarp [88,89] of plants, nut shells [94,143,[183][184][185], fungi [53,109,[186][187][188], abandoned food [96,131,189], shellfish [49,72,133], animal tissue [112,115,124], polysaccharide [44,85,147,155,190], protein [137].…”

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.

“…prepared activated carbon (AC) materials by a two‐step synthesis via carbonization followed by the KOH activation of rice straw in an argon atmosphere. Flute‐type microporous AC was successfully obtained from cotton stalks via the KOH chemical activation method . The assembled flute‐type micropore AC‐based electrode delivered a high specific capacitance of 254 F/g.…”

Dulse-derived porous carbon (DDPC)-polyaniline (PANI) nanocomposites were fabricated by a method based on the in situ chemical oxidation polymerization of aniline on DDPC. The characterization of the material showed that the nano-PANI was grown on the surface of DDPC in the form of nanosticks or nanoparticles. The DDPC-PANI nanocomposites were further used as electrode materials for energy-storage applications. Meanwhile, the effect of the amount of aniline on the electrochemical performance of DDPC-PANI was also investigated. The results show that a maximum specific capacitance of 458 F/g was achieved for the DDPC-PANI nanocomposites; this was higher than that of the DDPC electrode (218 F/g), and the PANI electrode (318 F/g). The specific capacitance of DDPC-PANI remained 66.0% of the initial value after 5000 cycles; this was higher than that of PANI (50.5%). Finally, a device of DDPC-PANI-activated carbon (AC) was assembled with DDPC-PANI as a positive electrode, which exhibited a high energy density of 9.02 W h/kg, which was higher than that of PANI-AC device.
