Abstract:
Lithium ferrites were synthesized by the use of sol-gel technique. X-ray
diffractometer (XRD) was used to confirm the crystal structure of spinal ferrites.
The evaluation of grain size and analysis of external surface morphology of
synthesized lithium ferrites was done by scanning electron microscope (SEM).
EDX was made to know about the elemental composition of the material used. To
analyze the Infrared absorption spectrum, Fourier transform infrared spectroscope
(FTIR) has been used. Magnetic characteristics such as saturation magnetization
(Ms), remenance (Mr) and coercive force (Hc) are calculated with a vibration
sample magnetometer (VSM). CV measurements were made, to know about the
electrochemical performance of the material. Cyclic Voltammetry (CV)
measurements were performed for the fabricated sample to scrutinize the
electrochemical kinetics. CV results show that with the increase in scan rate
specific capacitance decrease and area of the loop increases which is promising
for the formation of supper capacitors and lithium ion batteries (LIB).
