摘　　要：Well-crystallized FeSbO 4 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 FeSbO 4 unit with a specific discharge capacity of 1 100 1 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.FeSbO 4 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.Well-crystallized FeSbO 4 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 FeSbO 4 unit with a specific discharge capacity of 1 100 1 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.FeSbO 4 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.
