Abstract
Vanadium-doped LiFePO4/C used as a cathode for a lithium ion battery has been successfully synthesized. In this work, LiFePO4was 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 LiFePO4formation temperature is653.8–700.0
