Magnetic CoFe₂O₄ and NiFe₂O₄ Induced Self-Assembled Graphene Nanoribbon Framework with Excellent Properties for Li-Ion Battery.

ABSTRACT: A magnetically induced self-assembled graphene nanoribbons (GNRs) method is reported to synthesize MFe₂O₄/GNRs (M = Co,Ni). It is found that MFe₂O₄ compounds not only locate on the surface of GNRs but anchor on the interlayers of GNRs in the diameter of less than 5 nm as well. The in situ growth of MFe₂O₄ and magnetic aggregation at the joints of GNRs act as crosslinking agents to solder GNRs to build a nest structure. Additionally, combining GNRs with MFe₂O₄ helps to improve the magnetism of the MFe₂O₄. As an anode material for Li⁺ ion batteries, MFe₂O₄/GNRs can provide high reversible capacity and cyclic stability (1432 mAh g^-1 for CoFe
