Synthesis of carbon nanotubes on carbon fabric for use as electrochemical capacitor

Electrochemical Capacitors Based on Graphene Oxide Sheets Using Different Aqueous Electrolytes

“…This implies that the influence of the distributed capacitance on the double-layer formation of the GObased capacitor seems to become apparent. 29 The galvanostatic chargeÀdischarge measurements for the ECs fabricated with the GO electrodes were carried out at a current density of 0.5 mA/cm 2 , as shown in Figure 8. The curves illustrate that during the charging and discharging steps, the charge curve of the GO-based capacitor is generally symmetric to its corresponding discharge counterpart with a little curvature.…”

“…At a high scan rate of 50 mV/s, the delay for the current to reach a horizontal value near the reversal of the potential is observed. This implies that the influence of the distributed capacitance on the double-layer formation of the GObased capacitor seems to become apparent 29.…”

Compositional effects of PEDOT-PSS/single walled carbon nanotube films on supercapacitor device performance

“…The iR drop is attributed to a couple of factors including; (i) the contact resistance between PEDOT/PSS and SWNT, and (ii) contact resistance between the electrode material and current collector. 37,38 From Fig. 7, it can be seen that the largest specific capacitance is obtained for the 40% SWNT device and reaches 104 F g À1 at a current density of 0.2 A g À1 .…”

High-performance super capacitors based on activated anthracite with controlled porosity

“…In particular, the specific capacitances of the IMAC electrodes decreased rapidly, unlike the PMAC electrodes, with the increase in the current density from 0.2 A g -1 to 3.0 A g -1 . These results can be explained by the micro-and mesopore volume fractions of each electrode material [16,[27][28][29]. All of the PMACs have considerable micro-and mesopores, and the distribution of pore sizes was changing from micro-to mesopores according to the mass ratio of KOH to carbon.…”
