N2 - The characteristics of activated carbon pyrolyzed from rice husk used in the synthesis of LiFePO4/V/C for the development of lithium ion battery cathode has been examined. The synthesis was begun by synthesizing LiFePO4 (LFP) via hydrothermal route using the precursors in stoichiometric amounts of LiOH, NH4H2PO4, and FeSO4.7H2O. The assynthesized LFP was then added with variation of vanadium concentrations and a fix concentration of the carbon pyrolyzed from rice husk to form a composite of LiFePO4/V/C. The composites were characterized using X-ray diffraction (XRD), scanning electron microscope (SEM), and electrochemical impedance spectroscopy (EIS). The XRD results showed that the LiFePO4/V/C has been successfully formed whereas SEM results showed a difference in morphology of vanadium and activated carbon addition. The EIS results showed that the conductivity of LiFePO4/C-0 wt.% V is 1.0196×10-2 S/cm, LiFePO4/C-3 wt.% V is 1.0302×10-2 S/cm, LiFePO4/C-5 wt.% V is 6.1282×10-3 S/cm, and LiFePO4/C-7 wt.% V is 8.3843×10-3 S/cm. The best performance for lithium ion battery cathode was given by LiFePO4/V/C at 3 wt.% vanadium. This result indicated that rice husk can be used as a cheap resource for activated carbon in the development of lithium ion battery cathode.
