<P>Porous CoFe<SUB>2</SUB>O<SUB>4</SUB> nanoclusters with different concentrations of graphene based composites were synthesized by a simple solvothermal process. The electrochemical properties of prepared CoFe<SUB>2</SUB>O<SUB>4</SUB>–reduced graphene oxide (rGO) composites were evaluated using polyvinylidene fluoride and Na-alginate as binder materials. The CoFe<SUB>2</SUB>O<SUB>4</SUB> + 20% rGO composite with alginate exhibited a high stable capacity of 1040 mA h g<SUP>−1</SUP> at 0.1 C (91 mA g<SUP>−1</SUP>) rate with excellent rate capability. The observed enhancement in electrochemical properties of the CoFe<SUB>2</SUB>O<SUB>4</SUB> + 20% rGO composite with alginate is due to the high stability and good transportation network while charging–discharging.</P> <P>Graphic Abstract</P><P>Porous CoFe<SUB>2</SUB>O<SUB>4</SUB> nanoclusters with different concentrations of graphene based composites were synthesized by a simple solvothermal process. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c4nj00419a'> </P>
