“…In addition to the above challenges, extending the applications of BDCs is worth considering. The diversity in sources, species, structures, and compositions of biomass endows the composites with wide ranges of applications (Figure 17), such as in seawater desalination, 271 lead‐carbon batteries, 272,273 lithium‐ion batteries, 274,275 lithium–sulfur batteries, 276–278 lithium metal batteries, 279,280 sodium‐ion batteries, 275,281 oil/water separation, 87 and catalysts (or catalyst supports) 282,283 . For example, BDCs with high specific surface area with appropriate pore size and pore size distributions are beneficial for use in seawater desalination, water treatment, and oil/water separation.…”

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.

“…Small peaks at 2900–2920 cm −1 are assigned to the vibrations of C−H bonds. The peak observed at 1610–1634 cm −1 is allocated to the presence of carbonyl group and C=C stretching [22,23] . In addition, a small peak at 1390 cm −1 is ascribed to the overlapping of C−O stretching vibration while the broad peak at 1118–1080 cm −1 represents the C=O stretching vibrations [23,24] …”

Biowaste derived carbon materials are recently gaining attention owing to their high specific surface area (SSA) and decent electrical conductivity. Herein, pineapple peel derived porous carbon nanosheets have been synthesized at different activation temperatures (PP‐600, PP‐700 and PP‐800). This shows that its high SSA along with hierarchal pore size distribution makes it a suitable electrode material for supercapacitors. Further, the electrochemical performance of the as prepared electrode material was carried out in three different electrolytes viz. acidic (1 M H2SO4), basic (6 M KOH) and neutral (1 M Na2SO4) and among them 1 M H2SO4 electrolyte shows superior electrochemical performance. Furthermore, PP‐800 electrode material displayed highest specific capacitance of 368.8 F/g in 1 M H2SO4 electrolyte, which is much higher when tested and compared in 6 M KOH (34 F/g) and 1 M Na2SO4 (102.7 F/g) electrolytes at a constant current density of 1 A/g. Additionally, symmetrical solid‐state supercapacitor was fabricated by utilizing PP‐800 electrodes and PVA gel electrolyte, that rendered remarkable energy density of ∼43 Wh/kg at a high‐power density of ∼1 kW/kg. The as fabricated PP‐800//PP‐800 device displayed an extraordinary cycle life exhibiting capacitance retention of 83 % after 10000 ultra‐long charge‐discharge cycles.

“…Lead and carbon based hybrid supercapacitor obtained from orange peels exhibited 192 F g -1 at 10 A g -1 and also maintained the stability even after 10,000 cycles. With the help of B-doping and N-doping, hole density and carriers was getting improved, respectively [16]. Through the N-doping, wettability of the samples was increased, which further improve the specific capacitance.…”

This work focuses on the development of a novel type of chemically activated carbon networks composited with the graphene oxide. Here, the carbon networks were derived from green biomass wastes such as orange peels, banana peels and potato starch. All the obtained carbon materials were being activated using different activating agents based on the higher specific capacitance such as phosphoric acid activated orange peel derived carbon, sulphuric acid activated banana peel derived carbon and hydrochloric acid activated potato starch. Further they were individually composited with graphene oxide for enhanced performance. Different chemical activation is employed for the sake of obtaining higher specific capacitance, energy and power density. Phosphoric acid activation on orange peel derived carbon network was selected due to the improvement in the micropores and further increased the surface area with the controlling capability of structures of activated carbon. To improve the conductivity of the samples, graphene oxide was added. The electrochemical performance of orange peel, banana peel and potato starch derived nano porous activated carbon materials composited with graphene oxide for supercapacitor applications is evaluated using aqueous H2SO4 electrolytes at a scan rate of 10 mV s-1. The samples that are prepared are structurally characterized using fourier transform infrared spectroscopy, x-ray diffraction and electrochemically characterized using cyclic voltammetry, galvanostatic charge and discharge measurements, and electrochemical impedance spectroscopy. From the electrochemical measurements, suitability of material as electrode for supercapacitors can be understood. The superior electrochemical performance is attributed in orange peel derived nano porous carbon/ graphene oxide due to porous structure.
