Flexible α-Fe2O3 Nanorod Electrode Materials for Sodium-Ion Batteries with Excellent Cycle Performance

With the rise of flexible electronics, flexible rechargeable batteries have attracted widespread attention as a promising power source in new generation flexible electronic devices. In this work, [Formula: see text]-Fe2O3 nanorods grown on carbon cloth have been synthesized through a facile hydrothermal method as binder-free electrode material. The electrochemical performance measurements show that [Formula: see text]-Fe2O3 nanorods possess high specific capacitance and specific capacity retention of 119% after 100 cycles. The combination of low-cost and excellent electrochemical performance makes [Formula: see text]-Fe2O3 nanorods promising anode materials for sodium-ion batteries.
