Vanadium-doped LiFePO4/C
used as a cathode for a lithium ion battery has been successfully synthesized.
In this work, LiFePO4 was synthesized from LiOH, NH4H2PO4,
and FeSO4.7H2O at a stoichiometric amount. Vanadium was added in the
form of H4NO3V at concentration variations and 3 wt.%
carbon black. The characterization includes thermal analysis, X-ray
diffraction, electron microscopy, and electrical impedance spectroscopy. The
thermal analysis results showed that the LiFePO4 formation
temperature is 653.8?700.0°C. The X-ray
diffraction results showed an olivine structure with an orthorhombic space
group, whereas ...
