Description
Summary:In this study, we synthesized anode materials based on iron oxide (Fe<sub>2</sub>O<sub>3</sub>), titanium dioxide (TiO<sub>2</sub>), and reduced graphene oxide (rGO) via the electrophoretic deposition technique. The structural and morphological characteristics of electrodes were examined through various methods including SEM, XRD, Raman, and XPS. Among the investigated compositions, the three-component Fe<sub>2</sub>O<sub>3</sub>/TiO<sub>2</sub>/rGO electrode displayed superior electrochemical characteristics in comparison to the binary Fe<sub>2</sub>O<sub>3</sub>/rGO and TiO<sub>2</sub>/rGO electrodes. Specific capacities of 571, 683, and 729 mAh/g were achieved at 0.5 mA for the respective Fe<sub>2</sub>O<sub>3</sub>:TiO<sub>2</sub> molar ratios of 1:1, 2:1, and 3:1. The 2:1 ratio configuration offered the most promising balance between cycling stability and capacity, highlighting its potential as a high-performance anode in lithium-ion batteries. This work contributes valuable insights into the synergistic behavior of dual-transition metal oxides in composite electrode design using a low-cost and scalable method.
