摘要：
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.
