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.
