Abstract

A novel type of graphene-supported Fe₃O₄ nanohybrid, i.e. graphene wrapped single-crystalline Fe₃O₄ nanorods (Fe₃O₄@G nanorods), has been synthesized through a layer-by-layer assembly and a subsequent annealing approach. The as-synthesized Fe₃O₄@G nanorods have been used as anode materials for lithium-ion batteries, and manifest superior lithium-storage capabilities in terms of high reversible capacities, excellent capacity retention, and high rate capability.
