Background: CuFe2O4 nanoparticles possess good electrochemical properties apart from
their inadequate electronic conductivity and large volume variation. The resulting performance lag
can be modified by the addition of conductive materials to form a composite. Hence, the properties
of CuFe2O4/rGO nanohybrid are presented for application as anode material for lithium-ion batteries.
Methods: The composites are synthesized through a facile one-step method of thermochemical reaction.
The samples are characterized by X-ray diffraction (XRD), Scanning Electron Microscope
(SEM), Fourier transform infrared spectroscopy (FTIR), Dielectric behavior and Galvanostatic
Result & Conclusion: The XRD analysis confirmed the reduction of GO and formation of
CuFe2O4/rGO composite, whereas FTIR results showed two major vibrational bands that correspond
to spinel structure formation and attachment of rGO to CuFe2O4. The SEM images confirmed tethering
of CuFe2O4 nanoparticles with rGO sheets. It was also observed that the formation of the nanohybrid
of CuFe2O4 with rGO resulted in expected enhancement of the dielectric properties; dielectric
constant and AC conductivity. At 100 Hz frequency, the dielectric constant of the composite with 15
wt. % of GO was 1.27x105, which is higher than that of pure CuFe2O4 (3.57x104). The parameters
such as charge storage capacity and rate capability, which are reminiscent of battery performance
were also enhanced with the increase of rGO content in the composite. Hence, a substantial enhancement
of battery performance was depicted that projects the composite as a promising candidate
for applications in electrode material for lithium-ion batteries.
