Abstract
Porous CoFe2O4 nanoclusters with different concentrations of graphene based composites were synthesized by a simple solvothermal process. The electrochemical properties of prepared CoFe 2O4-reduced graphene oxide (rGO) composites were evaluated using polyvinylidene fluoride and Na-alginate as binder materials. The CoFe2O4 + 20% rGO composite with alginate exhibited a high stable capacity of 1040 mA h g-1 at 0.1 C (91 mA g-1) rate with excellent rate capability. The observed enhancement in electrochemical properties of the CoFe2O4 + 20% rGO composite with alginate is due to the high stability and good transportation network while charging-discharging. © 2014 the Partner Organisations.
