In this study, nitrogen-doped carbon composites were prepared by carbonizing 7,7,8,8-tetracyanoquinodimethane (TCNQ)-based metal-organic frameworks (MOFs) under a N 2 atmosphere.The TCNQ ligand and pyrolysis temperature played key roles in the formation of these N-doped carbon composities with various nitrogen contents and species, which can effectively adjust the electrochemical performances of electrode materials. The results showed that the nitrogen-doped carbon composites prepared via carbonization at 650 C (N-C-650), as the electrode material for supercapacitors, exhibited high capacitance of 223.7 F g À1 at a current density of 1 A g À1 , and the specific capacitance retained 73.4% of its initial capacitance after 3000 cycles. Moreover, the nitrogen-doped carbon composites prepared via carbonization at 550 C (N-C-550), as the anode material for lithium-ion batteries, exhibited a high reversible capacity of 675 mA h g À1 at a rate of 100 mA g À1 and excellent cycling stability (736.8 mA h g À1 after 50 cycles). The good electrochemical performance of the electrode materials was mainly attributed to the high nitrogen content and control over the type of nitrogen species in the nitrogen-doped carbon composites.

“…Typical values range from 5.8 % after 8000 cycles [72] to 3.5 % [73] with carbons and less than 1 % [74] or even no fading after 10,000 cycles with nitrogen-doped mesoporous carbons [75]. The beneficial effect of nitrogen doping has been stressed with reasons tentatively associated with electronic effects [47].…”

Supercapacitors are introduced and reviewed as devices with very high electric power capability suggested to support and supplement other devices for electrochemical energy storage and conversion with higher energy content but lower power. They are currently of significant importance on the device and local (end-user) level already providing resources to meet power surge demands. In larger mobile systems (vehicles) they help meeting this demand and also offer high power storage capabilities when braking. On an even higher level, they can provide support for maintaining power quality and help in peak shaving. A brief historic background and general information is followed by an overview of materials and their combination into already marketed devices and in possible systems under development.

“…[1][2][3][4][5][6][7] To further enhance the energy density and specific power of capacitors in nanoporous carbons, nitrogen doping is a quite promising method owing to its enhancing capacity, surface wettability, and electronic conductivity while maintaining the superior cycling stability. [8] Nitrogen-doping can be realized by carbonization of nitrogen-containing precursors, such as polypyrrole, [9,10] melamine-formaldehyde resin, [11] dopamine-modified polypyrrole, [12] urea formaldehyde resins, [13] biomass [14] or post treatment with ammonia gas. [15] However, the carbons directly derived from the above methods without further treatment usually have lower surface areas and smaller pore volumes, which are not suitable for supercapacitors.…”

Nitrogen-doped nanoporous carbons have been successfully synthesized by direct carbonization of a nitrogenrich metal-biomolecule framework, zinc glutamate (Zn(H 2 O)(C 5 H 7 NO 4 )•H 2 O), as a template without any additional carbon or nitrogen sources. The surface area and pore size distribution of the resultant carbon materials were studied based on the carbonization temperature. These carbons exhibited high specific surface area (as high as 1619.2 m 2 •g 1 for ZGC-1000). Furthermore, ZGC-1000 also provided a large specific capacitance of 140.8 F•g 1 at a current density of 0.25 A•g 1 when measured in a three-electrode system. It is believed that the presence of the nitrogen-doped nanoporous carbons prepared from the metal-organic frameworks will further facilitate the exploration of such materials as supercapacitors.
