Special Issue Information

Dear Colleagues,

There have been many studies indicating that supercapacitor energy storage could be used to advantage in electric and hybrid vehicles. Supercapitors can be used alone or in combination with batteries to improve the powertrain efficiency and/or to increase the cycle life and reduce the cost of the batteries. The automobile industry has shown minimal interest in using supercapacitors, even in their advanced, high efficiency, alternative fuel vehicles. The reasons given for not using supercapacitors are their relatively low energy density and the high cost of the supercapacitors and the interface electronics needed to control the power as the capacitor voltage decreases in discharge. This Special Issue will address topics of special interest for vehicle applications of supercapacitors with particular attention to those cited by the auto industry as reasons for rejecting them as components in electric and hybrid vehicle powertrains. These topics could include, but are not be limited to, the following:

  1. High energy density, high power, long life, low cost supercapacitor technologies;
  2. Performance and cost requirements for supercapacitors for use in vehicles;
  3. Energy storage (Wh) and power requirements for supercapacitors alone and in combination with batteries in HEVs, EVs, and PHEVs;
  4. Control and simulation of supercapacitors in vehicle applications;
  5. Battery cycling data showing the effect of the use of supercapacitors on battery cycle life;
  6. Trade-offs between energy density, power capability, cycle life, and cost of batteries for electric and hybrid vehicles of different all-electric range;
  7. Design, control, and cost of interface electrics for use with supercapacitors;
  8. Design and testing of vehicles using supercapacitors;
  9. Analysis and tests of stop-go hybrid vehicles using supercapacitors and batteries;
  10. Any topic related to the use of supercapacitors in vehicles.

Abstract

In this paper, ionic surfactants are employed to intercalate thermally-reduced graphene oxide (TRG). The ionic interaction between the intercalated surfactant and the ionic liquid could lead to the formation of large-sized ionic aggregates and, hence, enlarge the interlayer distance between the TRG sheets. The morphology and vibration modes of these composites were systematically characterized using XRD (X-ray diffraction), SAXS (small-angle X-ray scattering), and FTIR (Fourier transform infrared spectroscopy). An asymmetric supercapacitor, which consisted of a cationic surfactant-intercalated electrode on one side and an anionic surfactant-intercalated electrode on the other, was examined. It was found that, with the increased interlayer distance, the energy density and capacitance of the cells were improved. It seems that the cell with a cationic surfactant as the cathode had the best energy density of 67.8 Wh/kg, which is 4.4-fold higher than that of the TRG cell. Full article
