α-Fe2O3 nanorods have been successfully obtained by annealing α-FeOOH precursor nanorods synthesized by a facile hydrothermal method. The electrochemical performance of the as-prepared α-Fe2O3 nanorods as anode materials for sodium-ion batteries is tested using galvanostatic charge/discharge cycling. The result indicates that the pesudocapacitor effect dominates the charge/discharge process. The α-Fe2O3 synthesized at different temperature indicates that α-Fe2O3 with a high crystallinity manifests relatively better cycling performance with a capacity of 177 mAh g-1 after 20 cycles at current density of 200 rnA g-1. While the current density increases to 500 mA g-1, the corresponding discharge capacity can still remain as much as 132 mAh·g-1. Meanwhile, XPS spectrum results of the active electrode material asprepared and after a discharge process disclose that the electrochemical reaction mechanism happens in the half-cell sodium ion battery is the reduction of Fe2O 3 to Fe.
