Capacitance Properties of Electrochemically Synthesised Polybithiophene-Graphene Exfoliated Composite Films
The graphene (GR) has attracted intensive interest due to its two-dimensional and unique physical properties. In the present study, the graphene sheets were synthesized by electrochemical exfoliation of graphite in sulfuric acid solution. The polybithiophene-graphene (PbTh-GR) composite films deposited onto indium tin oxide substrate (ITO/PbTh-GR) have been prepared by the incorporation of ...

15 صفحه اولTetrabutylammonium Perchlorate electrolyte on electrochemical properties of spinel MgCo2O4 nanoparticles
Spinel magnesium Cobaltite (MgCo2O4) nanoparticles with a crystalline size in the range of ∼16 nm were prepared by a simple co-precipitation technique with NaOH as a precipitant. The formation of spinel MgCo2O4 phase was confirmed by X-ray diffraction (XRD) pattern. Scanning electron microscope (SEM) images showed that aggregated nanoplates. The elect...
متن کاملThe volumetric capacitance of microporous carbons in organic electrolyte
The study of 26 microporous carbons with average pore widths Lo between 0.7 and 1.8 nm shows that the volume-related capacitance Cmi(F cm) in the organic electrolyte (C2H5)4NBF4/acetonitrile is an inverse function of the average micropore width Lo. This means that for a given micropore volume Wo, the gravimetric capacitance C(F g) is larger for carbons with smaller pores due to the higher surfa...
