CNT@TiO(2) nanohybrids for high-performance anode of lithium-ion batteries

This work describes a potential anode material for lithium-ion batteries (LIBs), namely, anatase TiO(2) nanoparticle-decorated carbon nanotubes (CNTs@TiO(2)). The electrochemical properties of CNTs@TiO(2) were thoroughly investigated using various electrochemical techniques, including cyclic voltammetry, electrochemical impedance spectroscopy, galvanostatic cycling, and rate experiments. It was revealed that compared with pure TiO(2) nanoparticles and CNTs alone, the CNT@TiO(2) nanohybrids offered superior rate capability and achieved better cycling performance when used as anodes of LIBs. The CNT@TiO(2) nanohybrids exhibited a cycling stability with high reversible capacity of about 190 mAh g(-1) after 120 cycles at a current density of 100 mA g(-1) and an excellent rate capability (up to 100 mAh g(-1) at a current density of 1,000 mA g(-1)).
