A high full-electrode basis capacity secondary battery anode consisting of a template-free 3D nanostructured Fe3O4/C composite is presented. On a full electrode basis, the nanocomposite exhibits attractive electrochemical performance including a volumetric capacity of 1064 mAh cm(-3), which significantly exceeds both the practical (≈300 mAh cm(-3)) and theoretical (837 mAh cm(-3)) capacity of a commercial graphite-based anode.
Keywords: Li-ion batteries; anodes; conversion compounds; electrodes; energy density.
