One-pot synthesis of a FsGDY/Fe2O3 composite applied in lithium-ion batteries

Abstract

A novel FsGDY/Fe₂O₃ composite was synthesized via a one-pot method that enables the simultaneous hydrolysis of Fe ions and the coupling reaction of fluorinated GDY monomers. This solid-state procedure significantly improves the dispersion of Fe₂O₃ nanoparticles and expands the interlayer spacing of the FsGDY layers. These structural features, combined with the strong interaction between the two components, facilitate efficient electron and ion transport pathways. Consequently, the composite exhibits high specific capacity and prolonged cycling life as an anode material for lithium-ion batteries.
