摘要
在230℃,利用水热法将纳米氧化铁担载于石墨上制备了Fe2O3/石墨复合材料,运用X射线衍射和扫描电镜对其形貌和结构进行了表征,并研究了目标物作为锂离子电池负极材料的电化学储锂性能。研究结果证明,经50次循环后,复合材料的嵌锂容量维持在425mAh/g,远高于相同条件下石墨的252mAh/g和Fe2O3的108mAh/g。
Fe2O3/graphite composite was prepared by a facile hydrothermal method at 230℃. The morphology and structure were investigated by means of X-ray diffraction （XRD） and scanning electron microscopy （SEM）. The electrochemical performance of synthesized composite was studied as an cathode material for lithium ionic batteries. The electrochemical measurement results revealed that the composite had a excellent discharge capacity of 425 mAh/g higher than that 252 mAh/g of graphite and 108 mAh/g of Fe2O3 at the same current density after 50 cycles.
