In this paper, interconnected Fe3O4of carbon/nitrogen double-doped(Fe3O4/C/N)was prepared by a simple and efficient two-pot method. Profiting from the advantages of carbon/nitrogen double-doped and massively interconnected nanoarchitecture, Fe3O4/C/N was characterized and analyzed by XRD, XPS, TG, SEM and TEM.Fe3O4/C/N show excellent reversible capacity and exceptional cycle performance when used as anode materials for lithium ion batteries.The initial coulomb efficiency of Fe3O4/C/N is 73.9% and maintain capacity of 516mA•h/g after 210 cycles at current density of 0.2 A/g. The capacity retention is 64.6%, which equivalent to a small capacity decay of 0.17% per cycle. Therefore, as an anode material, Fe3O4/C/N has excellent application in lithium-ion batteries.
