CoFe(2)O(4)-Graphene Nanocomposites Synthesized through An Ultrasonic Method with Enhanced Performances as Anode Materials for Li-ion Batteries

CoFe(2)O(4)-graphene nanocomposites (CoFe(2)O(4)-GNSs) have been synthesized through an ultrasonic method combined with calcination process. The nanocomposite calcinated at 350 °C shows better rate capabilities, e.g., 696, 495, 308, and 254 mAh g(-1) at 1, 2, 5, and 10 A g(-1), respectively.
