Abstract:
Nickel ferrite (NiFe2O4) can be used as a high capacity electrode (anode) for LIBs. This
research aims to enhance the performance of LIB’s by using a composite of NiFe2O4 with
graphene oxide (GO). A facile hydrothermal process was used to synthesize NiFe2O4/GO
composite. This composite was fabricated further by using the nanoparticles of spinel
NiFe2O4 around 20 nm and varying quantity (1ml, 2ml and 3ml) of GO through
hydrothermal process. Different experimental techniques such as Fourier transform
infrared spectroscopy (FTIR), X-ray diffraction (XRD) and RAMAN were used to study
the structural and morphological properties of this composite. At the end, the impact of the
NiFe2O4/GO composite electrode on the working of lithium-ion batteries were studied
using CV measurements. The results show that a solo phase spinal structure was identified
by X-ray diffraction and lattice parameter (a) was gradually increased from 8.42 Å to
8.48Å. The FTIR shows the absorption band of octahedral site at about 597 cm-1
for pure
NiFe2O4 and this band moved in the direction of higher frequency by increasing the GO
concentration because substitution of GO reduces the bond length. Through cyclic
voltammetry the NiFe2O4/GO electrodes was measured as an anode for lithium ion
batteries that displayed excellent lithium storage enactment as well as good cycling
durability , high-rate proficiency and high-rate reversible capacity.
