Abstract

Mesoporous interconnected carbon-encapsulated Fe₃O₄ (Fe₃O₄@C) nanospheres assembled from tiny nanoparticle subunits have been synthesized by a one-pot solvothermal decomposition route followed by thermal annealing. Electrochemical characterization of these interconnected Fe₃O₄@C nanospheres exhibits a capacity of 636 mA h g⁻¹ at 0.2–1 C over 50 cycles when employed as anode materials in Li-ion batteries.
