High performance nitrogen-doped carbon for supercapacitor obtained by carbonizing eco-friendly and cheap polyaspartic acid

Nitrogen-containing carbon microspheres for supercapacitor electrodes

“…Nitrogen-containing carbon materials can be prepared by the carbonization of nitrogen-enriched polymers and materials, such as polyaniline, melamine, polypyrrole and so on [24][25][26][27][28][29][30][31][32]. It is believed that presence of nitrogen changes the electron donor/ acceptor properties of carbon materials, thus affects the formation of electric double-layers [33].…”

One-pot fabrication of Co3O4 microspheres via hydrothermal method at low temperature for high capacity supercapacitor

“…Due to the strong growth in demand for energy and the worsening global environmental problems, choose of alternative energy is impeding the sustainable development of human society [1][2][3][4][5][6][7][8][9][10]. The study focused on transitional metal oxide revealed that Co 3 O 4 is a promising optional candidate compared with carbon-base materials on account of the high capacitance (theoretical value to 3560 F/g) [11], excellent reversible redox behavior and good corrosion stability [12].…”

High Specific Capacitance Electrode Material for Supercapacitors Based on Resin-Derived Nitrogen-Doped Porous Carbons

“…Incorporating N atoms not only significantly promotes surface wettability, electrical conductivity, and cycle stability of carbon materials but also increases the pseudocapacitance through the Faraday reaction. , In general, a common strategy for preparing nitrogen-doped porous carbons (NPCs) is by utilizing reactive nitrogen sources to passivate carbon surfaces; another strategy is carbonization and activation of N-containing precursors . N-containing compounds are used as precursors to synthesize NPCs, thereby improving its electrochemical performance, for example, polyaspartic acid, ortho -aminophenol/formaldehyde resin, polypyrrole, polyacrylonitrile, and so forth. Zhou et al used m -aminophenol formaldehyde resin as a carbon and N source to obtain N-doped hierarchical porous carbon materials through precarbonization and KOH activation.…”
