Abstract

Nb₂O₅/C nanosheets are successfully prepared through a mixing process and followed by heating treatment. Such Nb₂O₅/C based electrode exhibits high rate performance and remarkable cycling ability, showing a high and stable specific capacity of ∼380 mAh g⁻¹ at the current density of 50 mA g⁻¹ (much higher than the theoretical capacity of Nb₂O₅). Further more, at a current density of 500 mA g⁻¹, the nanocomposites electrode still exhibits a specific capacity of above 150 mAh g⁻¹ after 100 cycles. These results suggest the Nb₂O₅/C nanocomposite is a high performance anode material for lithium-ion batteries.
