Abstract

TiO₂-B was synthesized by solid-state reaction. The structures, surface morphologies and electrochemical performances of TiO₂-B were characterized by X-ray diffractometry (XRD), scanning electron microscopy (SEM) and electrochemical measurement, respectively. The effects of calcining temperature, molar ratio of K₂O to TiO₂ and calcining time on the characteristics of TiO₂-B were investigated. The results show that the calcining time exerts a significant influence on the electrochemical performances of TiO₂-B. The TiO₂-B is obtained with good crystal structure and suitable size by using K₂Ti₄O ₉, which is prepared at 950°C for 24 h under the condition of x(K₂O)/x(TiO₂)=1:3.5. The TiO₂-B delivers all initial discharge capacity of 231.6 mA•h/g. And the rate capacity is 73.2 mA•h/g at 1 675 mA/g, which suggests that TiO₂-B is a promising anode material for the lithium ion batteries.
