Ni(OH)2 nanowires/graphite foam composite as an advanced supercapacitor electrode with improved cycle performance

Ni(OH)2 and NiO Based Composites: Battery Type Electrode Materials for Hybrid Supercapacitor Devices

“…In a few studies, the cycling performance was evaluated using cyclic voltammetry experiments with scan rates between 50 and 100 mV·s −1 . Galvanostatic cycling tests were performed at 1 A·g −1 [30,37,54,60,82], 5 A·g −1 [44,49,67,89] and 10 A·g −1 [14,16,17], as they were the most recurring values of current density. We have chosen to report the results for 10 A·g −1 current density in Figure 5, which shows the relative capacity (% of theoretical capacity as previously detailed) as a function of the number of cycles.…”

Facile one-pot synthesis of 3D graphite–SiO2 composite foam for negative resistance devices

“…The electronics of graphite, 1 carbon nanotubes, 2 fullerene, 3 and graphene 4 are generally well understood. Research on the electronics of carbon structures has focused on 3D carbon composites [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] in recent years.…”

“…[5][6][7][8][9][10] Another possible approach is to use graphite foam as a 3D carbon network or template for introducing guest molecules. [13][14][15][16][17][18][19][20] Graphite foam could be prepared by foaming organic precursors [21][22][23][24] such as sucrose 22,23 or bread, 24 followed by carbonization.…”
