title: T-Nb2O5quantum dots prepared by electrodeposition for fast Li ion intercalation/deintercalation.
abstract: T-Nb2O5quantum dots were electrodeposited on Ti nanorod arrays to prepare Ti@T-Nb2O5core-shell array electrodes. The particle size of T-Nb2O5could be manipulated by adjusting the depositing current density, and quantum dots several nanometers in size could be obtained at a deposition current of 6 mA cm-2. Benefiting from the ultra-small particle size of T-Nb2O5and the array structure, Ti@T-Nb2O5nanorod arrays exhibited good rate capability and durability when used as self-supported Li ion battery anodes. The arrays possessed capacities of 350 and 70 mAh g-1at rate currents of 0.06 and 30 A g-1, respectively. Furthermore, the electrodes maintained 500 cycles without obvious decay at a high rate current of 30 A g-1.
