Abstract
Well-crystallized FeSbO4 nanorods with rutile-like structure are synthesized through a solid-state reaction and used as cathode material of Li-ion battery for the first time. The obtained nanorods can react with ∼11 Li-ions per FeSbO4 unit with a specific discharge capacity of 1 100 mAh·g− between 0.1 and 2.0 V. Three discharge plateaus can be observed during the fully discharging process, but the reversible reaction with ∼1 Li occurs between 1.5 V and 4.5 V vs. Li+/Li, and the reversible capacity is only 50–80 1 mAh·g−. FeSbO4 nanorods have a stable cyclic performance between 1.5 V and 4.5 V and it can be used as cathode material for rechargeable Li-ion battery.
