摘要：
Fe3O4 fuzzy spheroids were synthesized by a facile solvothermal method. The as-prepared Fe3O4 fuzzy spheroids were investigated by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy, and the results showed that they had a spinel structure and a uniform particle size in the range of 120-200 nm. Results of electrochemical testing showed that the Fe3O4 fuzzy spheroids exhibited a high initial charge capacity of 980.6 mAh g(-1) and 949.5 mAh g(-1) after 165 cycles at a current density of 0.5 C at ambient temperature, as well as good rate capability. The improvement of reversible capacity and cyclic performance for the Fe3O4 nanoparticles could be attributed to the special fuzzy spheroid structure. (C) 2011 Elsevier B.V. All rights reserved.
