Description
Summary:Porous CoFe 2 O 4 nanoclusters with different concentrations of graphene based composites were synthesized by a simple solvothermal process. The electrochemical properties of prepared CoFe 2 O 4 –reduced graphene oxide (rGO) composites were evaluated using polyvinylidene fluoride and Na-alginate as binder materials. The CoFe 2 O 4 + 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 CoFe 2 O 4 + 20% rGO composite with alginate is due to the high stability and good transportation network while charging–discharging.
