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 (1.42×10 −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 ).
