不同铁/氮比FexN@N-CNF的协同储Li/Na特性
Synergistic Li/Na storage properties of FexN@N-C nanofibers with different Fe/N ratios
摘要
Abstract
By altering the calcination temperature and the amount of iron source added,a series of FN@N-CNF-X-T nanofibers were prepared by electrospinning-assisted calcination using ferric nitrate nonahydrate as the iron source,anhydrous ethanol and DMF as solvents.The products were characterized by X-ray diffraction(XRD)and scanning electron microscopy(SEM).Meanwhile,the electrochemical performance of different products was explored.The results showed that as the anode of lithium-ion batteries,FN@N-CNF-4-500 exhibited a first discharge capacity of 917 mAh·g-1,a first charge capacity of 453 mAh·g-1,and excellent cycling stability within the voltage range of 0.01~3.0 V and a current density of 0.1 A·g-1.As the anode of sodium-ion batteries,FN@N-CNF-4-500 showed a discharge capacity of 544 mAh·g-1 and relatively good cycling stability within the voltage range of 0.01~3.0 V and a current density of 0.1 A·g-1.The results indicate that FN@N-CNF-4-500 exhibits superior lithium/sodium storage properties.关键词
