摘要
采用静电纺丝法成功合成一维Fe2O3@C复合物纳米纤维,并探究此纳米纤维的电化学性能.XRD检测结果表明该纳米纤维属于立方晶系,P4132(213)空间群.SEM结果证实其形貌呈纤维状,纤维的直径为100～200nm.用此材料组装的钠离子电池在电流密度为100mA·g-1的条件下,首次充电比容量为317.8mAh·g-1,循环100圈后仍具有168.8mAh·g-1的充电比容量.
Abstract
One-dimensional Fe2O3@C composite nanofibers were synthesized by electrospinning,and the electrochemi-cal properties of the nanofibers were explored.XRD results show that the nanofibers belong to the cubic crystal system with P4132(213)space group.SEM results confirm that the morphology is fibrous,and the diameter of the fiber is about 100～200 nm.The sodium-ion battery assembled with this material has a charge specific capacity of 317.8 mAh·g-1 for the first time and 168.8 mAh·g-1 after 100 cycles of current density.
