Among a variety of host materials for lithium storage, titanium-niobium oxides exhibit great potential in application. Herein, Ti 2 Nb 10 O 29 nanowire is synthesized via an electrospinning method. Compared with bulk Ti 2 Nb 10 O 29 prepared by solid-state approach, the electrochemical properties of Ti 2 Nb 10 O 29 nanowire is better. According to the galvanostatic charging-discharging test, the initial capacity of 232.8 mAh g−1 for Ti 2 Nb 10 O 29 nanowire is displayed. Besides, it exhibits superior rate performance. With the current density set as 0.5, 1, 2, 3, 4 and 5 C, the Ti 2 Nb 10 O 29 nanowire can deliver the specific capacity of 251.3, 240.3, 221.8, 205.3, 188.1 and 174.5 mAh g−1, respectively. Furthermore, its cycling performance is superior. The capacity retention of Ti 2 Nb 10 O 29 nanowire is 85.90% after 900 cycles at 12 C, which is obviously superior than that of bulk Ti 2 Nb 10 O 29 (25.16%). Finally, a Ti 2 Nb 10 O 29 /LiCoO 2 full cell is fabricated, which exhibits excellent electrochemical performance, demonstrating its potential for practical application. [ABSTRACT FROM AUTHOR]
