Effect of Carbonaceous Materials on the Electrochemical Performance of Fe₂O₃/C as an Anode Material for Lithium-Ion Secondary Batteries

Abstract:

The iron oxide anode materials have attracted widespread attention in lithium-ion battery research field. The Fe₂O₃/C composite was synthesized via hydrothermal method and characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The XRD confirmed that the main crystallization phases of materials were Fe₂O₃. The Fe₂O₃/AC powders showed very uniform cube between 1 and 2 μm. Fe₂O₃/CNTs composites acted as a three-dimensional network wiring to connect Fe₂O₃ spheres. The electrochemical investigation indicated that the electrochemical performance of Fe₂O₃/CNTs materials shows a high specific capacity and an excellent cycling stability. The first reversible capacity of samples is 808.8 mAhg^-1 at the current density of 100 mAg^-1 between 0.01 and 2.5 V vs. Li/Li⁺.
