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+.
