“…AC’s curve shape was seriously deviated from the rectangle, which was due to the underdeveloped pore structure and the relatively low insufficient electrochemical performance as well as specific surface area. The curves of ACG, ACG-N-P, and ACG-N-P-Ni, whose capacitance was mainly provided by the electric double-layer capacitance, all showed a shape similar to a rectangle and obvious hump in the low potential region . This indicated that the addition of GO and the doping of N, P, and Ni atoms promoted the enhanced electrochemical performance of poplar powder.…”

Poplar powder was used as a raw material to prepare an electrode material in supercapacitors by doping modification, carbonization, and activation. The lignin-removed poplar powder was mixed with graphene oxide, melamine, and diammonium hydrogen phosphate and then compounded with nickel sulfate. Upon carbonization and activation with KOH, the composite becomes a hierarchical porous carbon material with a pore volume of 0.93 cm3 g–1 and a surface area of 1214.1 m2 g–1. At 0.5 A g–1 current per square meter, the specific capacitance was 407.5 F g–1. In addition, 92.6% of the capacitance remained even after 3000 charging and discharging cycles. There was an outstanding power and energy density of 12.32 W h kg–1 at 499.99 W kg–1 for a symmetric supercapacitor in 6 M KOH. Co-doped porous carbon with nitrogen, phosphorous, and nickel could be a good electrode material for energy storage devices.

“…The micropore structure ensures the large specific surface area and abundant porosity of the carbon material, both of which are crucial for energy storage. 21 Figure 2d−f shows the elemental mapping of C, O, and N, respectively. The results show that the prepared nitrogen-doped carbon materials have a uniform distribution of carbon, oxygen, and nitrogen elements, proving that the N atom was successfully doped.…”

Biomass is an ideal source for the preparation of electrode materials due to its abundant distribution, renewability, and low price. Carbon materials constructed by nitrogen doping can greatly improve the performance of electrode materials, provide additional pseudocapacitance, and expand the application of supercapacitors in practice. Nitrogen-doped walnut shell (WS) carbon materials were prepared by chemical cross-linking and KOH activation using WS and γ-polyglutamic acid as raw materials. The effects of the ratio for carbon and nitrogen source compounds and activation temperature on the morphology, pore structure, graphitization of the carbon materials, and their electrochemical properties were systematically investigated. Nitrogen-doped WS carbon materials possessed a unique 2D lamellar structure and a high specific surface area (1932 m2 g–1). The addition of heteroatoms increased the polarizability and conductivity of the carbon material and introduced additional pseudocapacitance as a result of the good electrochemical performance. At a current density of 0.5 A g–1, the specific capacitance of materials can reach 342.0 F g–1 with a capacitance retention rate of 73% (20 A g–1). After 8000 cycles, the capacitance loss is only 8%, providing excellent electrochemical performance.

“…Many studies have demonstrated the high potential of porous carbons possessing large specific surface areas, hierarchical pore structures, and appropriate heteroatom-doping in supercapacitor applications. 172–174 In particular, specific capacitance, rate capability and cycling stability are important performance indices. For the synthesis of porous carbons with the above-mentioned properties, it is necessary to utilize large amounts of chemical activators and heteroatom dopants.…”
