Summary:Hybrid materials of CoFe.sub.2O.sub.4 nanoparticles anchored on graphene prepared by a facile hydrothermal process was developed to be anode material for sodium-ion battery. The hybrid nano-structure of CoFe.sub.2O.sub.4/graphene not only could be useful to buffer electrode volume accompanying with Na.sup.+ insertion-extraction, but also could be beneficial to improve electrode electric conductivity and further keep graphene sheet separated to improve ion diffusion rate. Electrochemical measurements showed that the hybrid material anode displayed an excellent performance with a large reversible capacity of 330 mAh g.sup.-1 after 75 cycle times and a satisfactory rate capability of 170 mAh g.sup.-1 at 1 A g.sup.-1.
