“…This suggests the single layer in carbon may be realigned during the activation process, which sheds additional light on availability of the deep inserted lithium to be "exposed" for the electrochemical cycling [51]. In addition, the more developed porosity after activation provides more pathways to ensure easy accessibility of electrolytes and faster transportation of lithium ions, thus endowing activated carbons with enhanced capacities.…”

The KOH-activated sample demonstrated enhanced electrochemical performance due to its high surface area and abundant mesoporous structure. Bean-dreg-derived carbon materials used as superior anode material for lithium-ion batteries AbstractThe structures of modified carbons from bean dregs were regulated via graphitization treatment and chemical activation. The microstructure and electrochemical performance were studied using X-ray diffraction, Raman spectrometer, SEM and TEM techniques. The electrochemical performance was investigated using electrochemical methods. After heat-treatment at 2800 O C, the obtained BDC-2800 possessed a high degree of graphitization and showed an outstanding cycling performance, delivering capacity decay from 423 to 396 mAh g -1 at 0.1 C after 100 cycles. The chemical-treated carbons also demonstrated enhanced electrochemical performance, especially for the KOH-treated sample. The BDC-K displayed superior specific charge capacity of 801 mAh g -1 at 0.1 C, and showed an impressive rate capability of 643 mAh g -1 at 1 C. In addition, this sample delivered capacity retention of 94%after 500 cycles at 1 C. This good electrochemical performance was mainly due to its high surface area and abundant mesoporous structure.

“…Without involving the strong chemical reagent (e.g. KOH and NaOH) [10,14,16,[27][28][29][30][31] during the synthesis route as well as avoiding the tedious preparation procedures in the templating method [33][34][35], the "curing" method adopted here will present a simple and cost-effective method for the preparation of activation carbon from other biomass. In order to understand the transport kinetics of the PSC and PMC electrodes, EIS measurements are shown in Figure 4.…”

“…This is mainly due to their high electric conductivity, high specific capacity and excellent chemical stability. Among the carbonaceous materials, activated carbon species derived from the abundant natural bio-precursors, such as cotton wool [9], coffee shells [10], rice husk [11], alginic acid [12], pine cone flowers [13], have drawn much attention over the past years. Such kinds of materials often possess rich porous structures and high specific surface area.…”

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.

“…It is worthwhile to mention that the source of activated carbon from biomass is a natural and renewable one and the preparation process is eco-friendly. Agricultural and food wastes, including banana fiber and coffee bean, have been widely studied in the production of activated carbons [7][8][9][10][11][12][13].…”

A high-performance conducting polymer-activated carbon composite electrode material was prepared by potentiostatic deposition of aniline on a hierarchically porous carbon, which was carbonized from the natural bamboo. The obtained composite combined the contribution of the unique properties of the activated carbon and pseudocapacitance of the deposited polyaniline layer. This active material possessed excellent rate capability and good cycle performance, over 92% of the original capacitance is retained after 1,000 cycles. The energy density of the composite can reach 47.5 Wh kg −1 calculated only by active mass. It can be a good candidate for high-performance supercapacitor.
