“…Although a good correlation was observed between the Brunauer-Emmett-Teller (BET) surface area and the specific capacitance, the presence of nitrogen and its effect on the capacitive behavior was not discussed, which is most likely due to the fast release of nitrogen during the chemical activation with KOH. The preparation of the nitrogen-doped AC from prawn shells for the use as electrode in supercapacitors has been recently reported [29]. This material, containing 4 wt% of nitrogen, was highly oxidized (reaching 21 wt% of oxygen) due to the KOH activation used for the preparation of the porous carbons.…”

“…Because chitin is produced in huge amounts as a by-product in the food industry, its use as a precursor for carbon materials is interesting from economic and environmental perspectives. The preparation of ACs by the chemical activation of chitosan chars using Na 2 CO 3 , K 2 CO 3 , ZnCl 2 , or KOH as activating agents has been reported [24][25][26][27][28][29]. However, only limited investigations of their use as electrode materials for supercapacitors have been reported.…”

Nitrogen-containing activated carbons were prepared from chitosan, a widely available and inexpensive biopolysaccharide, by a simple procedure and tested as electrode material in supercapacitors. The physical activation of chitosan chars with CO 2 led to carbons with a very high nitrogen content (up to 5.4 wt%) and moderate surface areas (1000-1100 m 2 g -1 ). Only chitosan-based activated carbons with a similar microporous structure were considered in this study to evaluate the effect of the nitrogen content and distribution on their electrochemical performance. The N-containing activated carbons were tested in two-and three-electrode supercapacitors using an aqueous electrolyte (1 M H 2 SO 4 ), and they exhibited superior surface capacitance (19.5 lF cm -2 ) and pseudocapacitance compared to a commercial activated carbon with a negligible nitrogen content and similar microporosity. The low oxygen content and the presence of stable quaternary nitrogen improved the charge propagation on the chitosan-based carbons, which was confirmed by the high capacity retention of 83 %. The chitosan-based carbons exhibited excellent cyclic stability and maintained 100 % of their capacitance after 5000 charge/discharge cycles at a current density of 1 A g -1 . These results demonstrate the suitability of chitosan-based carbons for application in energy storage systems.Electronic supplementary material The online version of this article

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.

“…These biomasses contain rich chitin and protein. Moreover, the activation carbon from such kinds of marine biomass with high level nitrogen content is beneficial for improving lithium storage properties [14,15]. As aforementioned, searching a simple and effective method for the treatment of marine biomass become critically important.…”

“…In order to obtain high-performance activated carbon, several preparation methods have been developed. The common routes include: (i) the chemical activation of the biomass precursors with the use of strong chemical acid or alkaline reagent, like NaOH [14,15], KOH [16] and H 3 PO 4 [17]; (ii) the physical activation via the steam or CO 2 treatment [18,19]. However, these common routes often involve the use of strong chemical reagent in the chemical activation process and need multiple or even complex preparation procedures.…”

Porous carbon materials derived from the prawn shell (PSC) and prawn meat (PMC) have been successfully fabricated by a simple "curing" method, followed by an annealing process. The PSC and PMC are well characterized by XRD, Raman, SEM and TEM. Electrochemical measurements reveal that PSC and PMC deliver high initial discharge/charge capacities of 1735/878 mAh g -1 and 1132/674 mAh g -1 at 100 mA g -1 and maintain charge capacity retention of 84.2% and 40.3% after 90 cycles, respectively. Moreover, the PSC exhibits a high reversible capacity of 300 mAh g -1 after 50 cycles at 1000 mA g -1 . The outstanding electrochemical performance of PSC and PMC is attributed to the coherent interconnected porous structure and nitrogen doping, which is beneficial for fast penetration of electrolyte, rapid diffusion of Li + and creation of numerous active sites for Li + storage.
