摘要：
In the present work, TiO2-B nanowires have been successfully synthesized for the first time based on a topological conversion process by using titanate as a precursor and exhibited a length of several hundred nanometers and a width of approximately 10 nm. This resulted in excellent electron/ion transport properties and reaction kinetics in lithium intercalation. Consequently, as an anode material for lithium-ion batteries, TiO2-B nanowires exhibited an extraordinary rate performance and outstanding long-term cycling stability with a capacity of 192.4 mA h g(-1) after 3600 cycles at a rate as high as 10C.
