“…The voltage–time curves of the NPC are close to a linear shape, implying an outstanding electrical performance. The specific capacitance of the NPC-950-60 electrode calculated from the slope of the discharge curve was about 156 F g –1 at 0.1 A g –1 , which is higher than those of some other activated porous carbon materials. − Meanwhile, as shown in Figure c, there is still a specific capacitance of 135 F g –1 after the current density increases 50-fold (5 A g –1 ), which is equivalent to 87% capacitance retention, indicating its good rate capability. Additionally, the galvanostatic charge–discharge curves of the NPC-950-30, NPC-950-100, NPC-900-100, NPC-850-30, activated polypyrrole powder, and cPPA at different current densities (0.1–5 A g –1 ) are displayed in Figure S9.…”

A novel polypyrrole-based aerogel (PPA) with a three-dimensional structure is synthesized through a simple hydrothermal process of homogeneous dispersion consisting of pyrrole and a block copolymer, followed by freeze-drying. The block copolymer plays the role of dispersant, which can be ascribed to the hydrophilic− hydrophobic interaction between pyrrole-based units and the block copolymer. Compared with a conventional bulk polypyrrole powder, the PPA exhibits higher porous attributes, which provide favorable conditions to the subsequent activation procedure. A nitrogendoped porous carbon (NPC) with high porosity is then prepared after a physical activation treatment of PPA using carbon dioxide as an activation agent. The structure and porous property of the NPC are characterized by scanning electron microscopy, transmission electron microscopy, infrared spectroscopy, X-ray photoelectron spectroscopy, and nitrogen adsorption−desorption experiments. The as-made NPC-950-100 possesses a large Brunauer−Emmett−Teller specific surface area (2330 m 2 g −1 ), large pore volume (2.54 cm 3 g −1 ), and nitrogen doping (4.1 wt %). These properties result in a high carbon dioxide uptake capacity of 20.5 wt % at 273 K and 1.0 bar. Furthermore, NPC-950-60 also displays a decent specific capacitance (156 F g −1 at 0.1 A g −1 ) and an excellent long-term cycling stability (∼100% capacitance retention at 5 A g −1 after 10000 cycles).

“…The C sp value of the electrode was computed as 12.9 F g −1 with a CD of 0.5 A g −1 . Likewise, Wu et al 15 developed a graphitization process of D-glucose-derived carbon by NaOH activation at elevated temperatures (600−900 °C). A maximum SSA of 1310 m 2 g −1 yields a high C sp of 106 F g −1 in the 6.0 M KOH electrolyte and retains 70% capacity retention at a scan rate of 2.0 V s −1 , which provides a low-cost technique for synthesizing high-performance electrode materials for SCs.…”

In this work, the preparation of porous carbon obtained from teak (Tectona grandis) leaves is reported and used for supercapacitors (SCs). The teak leaf carbon (TLC) was prepared using the biowaste as the carbon source precursors by NaOH activation and pyrolysis at 700−1000 °C under a nitrogen atmosphere. The crystallinity, structural features, textural properties, and thermal stability of TLCs were characterized by a variety of state-of-the-art techniques. Further electrochemical (EC) measurements, such as cyclic voltammetry, electrochemical impedance spectroscopy, and galvanostatic charge−discharge using a three-electrode setup, were done. The TLC-900 has micro-and mesoporous materials with large surface areas and pore volumes as high as 1692.6 m 2 g −1 and 0.86 cm 3 g −1 , respectively. Also, they exhibit remarkable EC and capacitive properties, achieving a maximum high specific capacitance (C sp ) of 310 F g −1 with a current density of 1.0 A g −1 in a 3.0 M KOH solution. Notably, TLC-900 attained a EC stability, achieving 123% retention in the same electrolyte after 10,000 cycles at a current of 1.0 A g −1 . As a result, the fabricated device displayed a maximum energy density of 24 W h kg −1 and power density of 1818 W kg −1 at a current density of 10 A g −1 . These outstanding EC behaviors, oxygen-containing functional groups, and structural characteristics of this porous carbon material indicate that TLCs are attractive for the fabrication of future large-scale industrial SCs.
