Electrical Properties Analysis of Magnetite (Fe3O4) Nanoparticles Doped with PVDF/rGO as Lithium-Ion Battery Electrode Material Application

Abstract

Lithium-ion batteries have high energy capacity, long life cycle and low environmental impact. However, the battery type is relatively expensive. One of the solutions to make it affordable by obtaining the nanoparticles electrodes from natural materials, namely iron sand (Fe₃O₄). To maximize the performance of Fe₃O₄, it is combined with PVDF and rGO using the sol gel method. It was conducted by the characterization a test using XRD and SEM on Fe₃O₄ nanoparticles and Fe₃O₄/PVDF nanocomposites with the ratio of 10:10, 10:20 an 10:30. The results of XRD and SEM characterization test showed that the nanocomposite had been formed and interaction between Fe3O4 and PVDF polymer with the best ratio at 10:30. An LCR meter used to obtain the electrical properties (capacitance, inductance and resistance) of Fe₃O₄/PVDF nanocomposite and Fe₃O₄/PVDF:rGO nanocomposite. The best result of the Fe₃O₄/PVDF nanocomposite from LCR meter have ratio at 10:30 with capacitance value at 37.01 pF, inductance at 0.23 uH and resistance at 0.032 Ω. The result of the Fe₃O₄/PVDF:rGO nanocomposite from LCR meter showed the ratios of 10:30:10, 10:30:20 and 10:30:30 and the best ratio was at 10:30:10 with capacitance value at 86.04 pF, inductance at 0.045 uH and resistance at 0.084 Ω.
