摘要
This research created a self-supporting material composed of Fe2O3 nanorods and 3D graphene foam (3DGF). The graphene foam which was intimately combined with the Fe2O3 nanorods effectively alleviated the volume expansion and increased the cycle stability. The graphene foam framework offered a continuous electron transfer pathway that enhanced the conductivity of the electrode material. Fe2O3@3DGF annealed at 400°C exhibited superior sodium storage properties with a high reversible capacity of 398 mAh·g-1 after 200 cycles at a current density of 500 mA·g-1.
