Abstract

Nano-sized TiO₂ powders were prepared by a hydrothermal synthetic method for use as anode materials in lithium secondary batteries. The prepared TiO₂ samples were characterized by X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) analysis, transmission electron microscopy (TEM), and electrochemical tests. TiO₂ nanoparticles were obtained at sintering temperatures between 200 and 600 °C. Calcination of the powders at 500 °C results in the formation of TiO₂ nano-sized particles of 22 nm in crystal size. These deliver a reversible discharge capacity of over 170 mAh g^-1 between 1.5 and 3.0 V with excellent capacity retention over 95% after 100 cycles. It is speculated that the nano-sized TiO₂ powders are effective candidates for lithium secondary anode materials.
