Abstract
Nanorod-shaped NaFeSnO4 having a tunnel-structure analogous to CaFe2O4 is proposed as a novel anode material for rechargeable sodium-ion batteries. The material shows a considerably high charge capacity of 179 mAhg?1 with low redox voltages, decent rate, and cycling performance. XANES results reveal Fe3+/Fe2+ as the active redox couple associated with the sodium insertion/extraction during cycling.
