In this paper, rutile TiO2 nanorod arrays are fabricated by a template-free method and proposed as a promising anode for aqueous Li-ion battery. The as-prepared TiO2 nanorod arrays exhibited reversible Li-ion insertion/extraction ability in aqueous LiOH electrolyte. Moreover, galvanostatic charge/discharge test results demonstrated that the reversible capacity of TiO2 nanorods could reach about 39.7 mC cm(-2), and 93.8 % of initial capacity was maintained after 600 cycles at a current density of 1 mA cm(-2) (= 240 C rate), indicating excellent cycling stability and rate capability.
