“…The low capacitance of C-500 may be attributed to its negative characters such as the wide pore size distribution (2.0$28 nm), low N content (3.44%) and low N-Q percentage (8.51%). As previously reports, the micropores (<2 nm) are the most effective in a double-layer formation, and N groups (especially N-Q group) help in electron transfer through the carbon to increase the pseudocapacitive interactions [22,28,33]. H 3 PO 4 /C-500 presents the highest performance for 260, 206, 187, 175, 169 and 156 F g À1 at the current density of 0.05, 0.1, 0.2, 0.5, 1.0 and 2.0 A g À1 , respectively.…”

“…The G-band observed at 1600 cm À1 has been assigned to the Raman-allowed phonon E 2g (stretching) mode of graphite. The strongest peak of G-band in the spectrum indicates the formation of good arrangement of hexagonal lattice of graphite [31]. The band at 1350 cm À1 corresponds to the D-band and assigned to the A 1g phonon is weak which reveals the high purity of the synthesized GMC.…”

“…The mesoporous carbon, especially with 3D configurations, can buffer electrolytes to reduce ion transport resistance and ion diffusion distance for high-rate SCs applications, and the large accessible specific surface area of mesoporous can also enhance the charge storage [14,15]. Benefiting from the aforementioned characteristics, the specific capacitance of mesoporous carbon could reach 100-290 F/g even in aqueous electrolytes [16][17][18].…”
