Abstract: The 1-stage FeCl₃-intercalated graphite intercalation compound (FeCl₃-GIC) were prepared by a molten salt method using FeCl₃ and natural flake graphite as raw materials. Subsequently, a conductive layer of polypyrrole (PPy) were uniformly coated on the surface of the FeCl₃-GIC particles by in-situ polymerization to form a core-shell structured (FeCl₃-GIC)@PPy composite material. Various characterization methods were employed to study the surface morphology and microstructure evolution of FeCl₃-GIC before and after polypyrrole coating. The results show that a uniform and dense polypyrrole layer with a thickness of 35 nm is tightly coated on the surface of the micro-sized FeCl₃-GIC particles. After coating, the conductivity of the (FeCl₃-GIC)@PPy composite is significantly improved for the powder resistivity is reduced from 3.1×10⁻³ Ω·cm of FeCl₃-GIC to 2.3×10⁻³ Ω·cm of (FeCl₃-GIC)@PPy. As an anode material for sodium ion storage, it is found that the (FeCl₃-GIC)@PPy anode exhibits the improved reversible capacitiy, rate capability and cycling stability compared with the naked FeCl₃-GIC anode. Specially, the specific capacity of (FeCl₃-GIC)@PPy remains steady with a high sodium storage value of 281 mA·h·g⁻¹ after 100 cycles at the current density of 0.1 A·g⁻¹, while the FeCl₃-GIC anode shows a continuous capacity decay with a low value of 157 mA·h·g⁻¹ after 100 cycles. Additionally, even at a high current density of 1.0 A·g⁻¹, the (FeCl₃-GIC)@PPy anode delivers a remained sodium storage capacity of 181 mA·h·g⁻¹ after 500 cycles, accompanying with a fascinating capacity retention ratio of 89%.
