Microwave-Synthesized TiO2Nanotube as a Durable Li+-Storage Electrode Material

TiO(2)nanotube (TNT) is synthesized by a facile microwave method. Physical properties of TNT are characterized by transmission electron microscopy, X-ray diffraction, Raman, thermal gravimetric analysis-differential scanning calorimetry, X-ray photoelectron spectroscopy, and nitrogen adsorption-desorption. Meanwhile, the electrochemical and kinetic performances are investigated. TNT anode in lithium-ion batteries exhibits a long cycling life (71 mAh g(-1)after 20000 cycles at 3 A g(-1)), outstanding rate capability (123 mAh g(-1)at 5 A g(-1)), and fast Li+-transport (1.42x10(-13) cm(2) s(-1)by EIS). Furthermore, TNT anode in dual-ion batteries also displays superior cyclic stability (75 mAh g(-1)after 1000 cycles at 0.5 A g(-1)).
