“…The pore size distribution is shown in Figure 3 sample. From these observations we conclude that the large specific surface area and the large composition of mesopores which provides a more suitable and favourable pathways for electrolyte penetration could facilitate fast ion transport and give rise to the excellent electrochemical property of the electrode material which is beneficial for high performance supercapacitors [39].…”

We present the electrochemical results of highly porous and interconnected carbon material by activation of graphene foam/polyvinyl alcohol-formaldehyde composite material designated as GF/PVA-F. Asymmetric supercapacitor devices were fabricated using the activated material (GF/PVA-F) and activated carbon (AC) as the positive and negative electrodes respectively. The device exhibited a maximum energy density of 42 mWh cm -2 , a power density of 0.5 W cm -2 and 98% retention of its initial capacitance after 2000 cycles in an extended cell potential window of 1.8 V in 1 M Na 2 SO 4 aqueous electrolyte. This work shows the great potential of this material for high performance energy storage application.

“…Furthermore, we studied the durability of the N-PCs-700 electrode using 12 galvanostatic charge/discharge measurement to characterize the long-term charge/discharge behavior at a current density of 1.0 A g -1 . As shown in Figure S3, the specific capacitance still remains at about 239 F g -1 (above 93% of the initial capacitance) after 5000 cycles, which illustrates that the N-PCs-700 electrode displays a good cycling and stability behaviors as the supercapacitor electrode material.…”

“…[1][2][3][4][5], carbon foams have attracted considerable attention in the past decades. Those features make carbon foam suitable for applications in energy storage, heat exchanger, filters, catalyst supports, and so on [6][7][8][9]. However, some of their properties are still not satisfying enough for specific application requirement, particularly mechanical property, electrical conductivity, and thermal conductivity.…”

The multi-wall carbon nanotube-reinforced carbon foams were prepared via foaming, carbonization, and graphitization process using pretreatment pitches as matrix precursor and modified multi-wall carbon nanotube as additive. The effects of modified multi-wall carbon nanotube additive amount on the microstructure, mechanical strength, thermal conductivity, and electrical conductivity of carbon foams were investigated by X-ray diffraction, scanning electronic microscopy, universal testing machine, laser thermal conductivity tester, and fourprobe resistance meter, respectively. It was found that the introduction of modified multi-wall carbon nanotube had a significant effect on the microstructure of carbon foams. The compressive strength and electrical conductivity of carbon foams increased with the increase of modified multiwall carbon nanotube additive amount, the maximum were 11.72 MPa and 28.89 9 10 3 S/m, respectively. However, the thermal conductivity of carbon foams increased firstly with increasing modified multi-wall carbon nanotube additive amount up to 2 wt%, and then decreased.
