Abstract

Fe ₃O ₄ fuzzy spheroids were synthesized by a facile solvothermal method. The as-prepared Fe ₃O ₄ 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 Fe ₃O ₄ 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 Fe ₃O ₄ nanoparticles could be attributed to the special fuzzy spheroid structure. © 2011 Elsevier B.V. All rights reserved.
