One-pot synthesis of Fe2O3/graphene and its lithium-storage performance

- Fe2O3/graphene composite was prepared by a facile one-pot hydrothermal process.
- Fe2O3 nanoparticles with diameter of 40-60 nm anchors on the graphene sheets.
- Fe2O3/graphene composite shows excellent lithium storage property.
- Electrochemical impedance spectra were analyzed.
