“…component in P500, while with further increasing the activation temperature, P-I disappears and P-IV appears in the carbon structure and reach the highest value in P900 because P-I is easy to decompose at high temperature. In addition to the presence of P-IV, the chemically adsorbed water and oxygen content is relatively high in P900 which could be attributed to the desiccant effect of P 4 O 10 [8]. The double bonded oxygen C=O, P=O (O-I) is the main component in carbon P800, while the nitrogen functional groups are mainly in N-5 and N-Q.…”

“…If some phosphorus functional groups can be present in the carbon lattice at the same time, it will inhibit the occurrence of certain side effects, such as oxidation of carbon electrode [5,7,8], thus increasing the potential operation window, cycle stability and energy density of the SCs. In this respect, functionalization of carbonaceous materials with heteroatoms, such as phosphorus [5,8], nitrogen [9,10], boron [11], sulphur [12] and dual heteroatom co-doped carbon materials [13][14][15] have been recently studied as electrode in SCs. Besides the surface chemistry, the porous structure of carbon electrode can also greatly influence the electrochemical performance of the SCs.…”

“…It is obvious that the N-CNWs-700 symmetric cell exhibits the highest energy density of 15.8 Wh kg -1 with a power density of 450 W kg -1 and remained 7.8 Wh kg -1 at 9145 W kg -1 . Moreover, the obtained maximum energy density is considerably higher than those of recently reported symmetric cells, such as AC//AC (10 Wh Kg -1 )28 , MC//MC (7.84 Wh Kg -1 )29 , MCSF//MCSF (9.6 Wh Kg -1 )30 phosphorus-rich carbon symmetric cell (13 Wh Kg -1 )31 .…”

We introduce a facile integrated oxidation polymerization and catalytic carbonization method to prepare three-dimensional porous nitrogen-doped carbon networks (3D N-CNWs) with high nitrogen content (about 8.4 wt%) directly from poly(p-phenylenediamine).In synthesis process, the FeCl 3 not only serves as an oxidant for oxidative polymerization of pphenylenediamine monomers but also as the carbonization catalyst to promote porous carbon networks formation. The 3D N-CNWs prepared at 700 o C exhibit an interconnected porous framework with high specific surface area and shows remarkable performances as an electrode material for supercapacitors. The maximum specific capacitance of 304 F g -1 at a current density of 0.5 A g -1 , and retains the high values of 226 F g -1 even at a high current density of 20 A g -1 is obtained for the N-CNWs electrode in 6 M KOH aqueous solution. Moreover, the as-assembled N-CNWs symmetric supercapacitor exhibits a considerably high energy density of 15.8 Wh kg -1 at a power density of 450 W kg -1 operated in the voltage range of 0-1.8 V in 0.5 M Na 2 SO 4 aqueous solution, and exhibits an excellent cycling performance with 97% specific capacitance retention after 5000 cycles.

“…As illustrated in the use of an amount of phosphoric acid as high as 50 wt.% notably reduces components O1 (C=O bonds in carbonyl and carboxylic acid) and O3 (non-carbonylic C-O bonds in ester and anhydride functionalities), while a significant increase in the O2 peak takes place. The latter is associated with esters, anhydrides and hydroxyl functional groups and also to the bridging oxygen in phosphates/polyphosphates (C -O -PO 3 )[32,33].…”

Carbon based-supercapacitors are widely used in numerous applications but the knowledge of the specific role of carbon features in their performance is still insufficient. The main aim of this work is to warn readers that the current interpretation of the device operation, mostly based on powdered carbon properties, may be misleading in certain cases and should be complemented with the physicochemical characterization of the corresponding electrodes. Ordered mesoporous carbons highly enriched in surface functionalities were prepared by carbonization of 3aminobenzoic acid into SBA-15 template. These carbons achieved a specific capacitance as high as 220 F/g in 2M H 2 SO 4 aqueous electrolyte. The pseudocapacitance contribution ranged between 35 and 70% of the overall capacitance. It was shown that the structural and textural changes underwent by these advanced carbons during their processing in form of electrodes prevented the full exploitation of their outstanding properties for high-power applications. This makes a difference regarding conventional, disordered activated carbons, which virtually preserve their structure during electrode preparation.
