Atmospheric-pressure plasma jet processed SnO2/CNT nanocomposite for supercapacitor application

A tin(iv) oxides/carbon nanotubes composite with core-tubule structure as an anode material for high electrochemistry performance LIBs

“…3, it can be seen that the main mass loss occurred in the range of 200-800 C, which is caused by the combustion of CNTs in the composite. 28,30 So, the content of SnO 2 in the SnO 2 /CNTs composite is about 74.3 wt%, 66.4 wt% and 55.3 wt% respectively when the reaction time is 100 h, 64 h and 24 h. These data suggest that the content of SnO 2 lled in the cavity of CNTs will increase with the increase of reaction time, which will result in the increase of charge & discharge capacity of the composite.…”

“…27,28 Usually electrochemical deposition, solution-chemistry method and capillary forces action (physical deposition) are regarded as the commonly used techniques. 29,30 Herein, we reported a special structure of SnO 2 /CNTs coretubule composite and studied the effect of reaction times on the electrochemical performance of the composite as anode materials for LIBs.…”

The preparation and characterization of SnO2/rGO nanocomposites electrode materials for supercapacitor

“…Figure 7(a) is the CV curve of both composite electrodes at the scanning rate of 50 mV s À1 in the potential range of À0.8 to 0.4 V, the larger area of the CV curve of SGT composite materials indicated the higher specific capacitance, which is consistent with the GCD results. In addition, the CV of SGT composites is performed at different scanning rates (5,10,20,50, and 100 mV s À1 ), as shown in Figure 7(b). The CV curve shows a good symmetry, which indicates that the composite material has good reversibility as the electrode.…”

“…4 The nanoporous SnO 2 /carbon nanotubes composites for supercapacitor application show the 188.42 F g À1 at a potential scan rate of 2 mV s À1 . 5 For many of these composites materials, many studies show that graphene is an effective conductive substrate for further construction of the high-quality SnO 2 nanomaterials. 1,[6][7][8][9][10][11][12] The preparation of SnO 2 /graphene composites can not only effectively prevent the reunion of SnO 2 nanostructures and stack of graphene resulting the larger electrical activity surface area but also improve the electrical conductivity and mechanical stability of composite material, which is good for the transport of ionic and the improve of electrochemical performance.…”

Scan-Mode Atmospheric-Pressure Plasma Jet Processed Reduced Graphene Oxides for Quasi-Solid-State Gel-Electrolyte Supercapacitors

“…Some APPs possess slightly higher electron density and moderate gas temperature of the order of hundreds of degrees Celsius. In such APPs, the synergetic effects of reactive species and heat trigger high plasma-chemical reactivity, thus affording ultrafast materials processing capability [12][13][14][15][16][17][18][19][20]. For example, a DC-pulse nitrogen APPJ shows high reactivity with carbonaceous materials and the processing times for carbon nanotubes (CNTs) and reduced graphene oxides (rGOs) are within 30 s [12,15,[18][19][20][21][22].…”
