Abstract

Fe304 -carbon composite was prepared by the sol-gel method. The crystal structure, morphology, and phases present in the product were investigated by X-ray diffraction and by scanning electron microscopy (SEM) combined with energy dispersive X-ray spectroscopy and field-emission SEM. Electrochemical characterization was performed using constant current charge-discharge testing and electrochemical impedance spectroscopy. The Fe304/C electrode has high initial columbic efficiency (87%) and outstanding cycling performance (775.3 mAh g-1 after 90 cycles at a current density of 100 mA g-1).
