用于锂离子电池的Fe3O4/C纳米结构的可控制备
Morphology-controlled synthesis of Fe 3 O 4/carbon nanostructures for lithium ion batteries
摘要
Abstract
Morphology-controlled Fe3 O4 / carbon nanocomposites were synthesized by a solvothermal reaction followed by calcina-tion under a nitrogen atmosphere. Flower-like structures, dispersed nanoflakes and hollow microspheres could be readily obtained by adjusting the concentrations of the reactants. Based on the time-dependent structure evolution, a possible mechanism for the forma-tion of the different morphologies under various conditions was discussed. The lithium storage properties of the different Fe bon composites were compared. The flower-like sample shows the best electrochemical performance with the highest specific capaci-ty of 227 mAh/ g at a current rate of 5 C while hollow microspheres and dispersed nanoflakes have specific capacities of only 45 and 10 mAh/ g, respectively.关键词
