Abstract:
Na(2.65)Ti(3.35)Fe(0.65)O9 rods were prepared by a simple solid-state route and coated with carbon to enhance their electronic conductivity. For the first time, Na(2.65)Ti(3.35)Fe(0.65)O9 was explored as an anode material for Na-ion batteries to deliver a discharge capacity of 137.5 mA h g(-1) at a current rate of 40 mA g(-1). The charge/discharge capacity of a carbon-coated sample increased by 46.3% to achieve 201.1 mA h g(-1).
