摘要：

Ti2Nb10O29 is fabricated directly by solid-state reaction from commercial TiO2 and Nb2O5. Without further modification, the bulk Ti2Nb10O29 anode exhibits a reversible capacity of 144 mA h g(-1) at 10 C after 800 cycles. More impressively, the capacity of the Ti2Nb10O29/LiFePO4 full-cell at 1 C stabilizes at 100 mA h g(-1) after 1000 cycles.
