“…Similarly, the calculated areal (volumetric) energy of the devices are 0.6 (41), 0.9 (62) and 2.45 μWh cm −2 (166 μWh cm −3 ) for GO, RGO and OFRGO, respectively. Compared to RGO and GO, the OFRGO exhibits highly improved energy density and comparable with the reported results . Overall, it can be realized that the basic oxygen functional groups played a vital role for the improved electrochemical performance of the device.…”

“…Compared to RGO and GO, the OFRGO exhibits highly improved energy density and comparable with the reported results. [17,18] Overall, it can be realized that the basic oxygen functional groups played a vital role for the improved electrochemical performance of the device. The obtained length capacitance is higher than or comparable with the previous reports.…”

“…[29] The MnO 2 flexible solid state supercapacitor exhibits the areal capacitance of 20 mF cm À2 at 10 mV s À1 . [18] The graphene oxide / poly(3,4-ethylenedioxythiophene) / carbon nanotube based ternary composite showed the volumetric capacitance of 2.7 F cm À3 at 0.042 A cm À3 . [30] The obtained improved performance of OFRGO is may be due to the synergistic effect of oxygen functional groups and RGO sheet.…”

Tracking the interfacial charge transfer behavior of hydrothermally synthesized ZnO nanostructures via complementary electrogravimetric methods

“…[4][5][6][7] Generally, metal oxides can offer higher energy density than conventional carbon materials and better electrochemical stability than conducting polymers. 2 To date, transitional metal oxides, such as ruthenium oxide (RuO 2 ), 8 manganese dioxide (MnO 2 ), 9 zinc oxide (ZnO) 10 and nickel oxide (NiO) 11 have been intensively studied as electrode materials, which can offer additional pseudocapacitances during electrochemical performance.…”

Breathable 3D Supercapacitors Based on Activated Carbon Fiber Veil

“…With the bloom of self‐powered wearable electronics, supercapacitors of high power density, fast charging and discharge capability, and long cycle life have drawn much attention as a promising class of energy storage devices that bridge the gap between lithium‐ion batteries and conventional electrostatic capacitors . In the recent years, great efforts have been particularly devoted to the development of lightweight and flexible electrode materials with high capacity for practical applications of supercapacitors . Despite their achievements, most electrode materials to date are susceptible to fracture under anomalous mechanical deformations to which our daily garments are frequently subjected such as folding, cutting, and pressing.…”
