ZnFe2O4/C composites have been prepared through a molten salt route combined with a carbonization process using glucose as carbon source. The field emission scanning electron microscopy and transmission electron microscopy confirm that the as-prepared ZnFe2O4/C is composed of nanodiscs with the thickness of 100-200 nm. The electrochemical measurement depicts that the ZnFe2O4/C electrode exhibits good cycle ability and rate capacity. A specific capacity of 965 mAh g(-1) can be maintained after 100 cycles at the current density of 100 mA g(-1). When the current density is increased to 2000 mA g(-1), the specific capacity still remains at 595 mAh g(-1) after 50 cycles. (C) 2015 Elsevier B.V. All rights reserved.
