In this work, Li₂CoTi₃O₈ nanofibers and Li₂CoTi₃O₈·CoTiO₃·TiO₂ (LCT) composite nanofibers as anode materials in lithium-ion batteries (LIBs) were successfully prepared by a traditional electrospinning technology, and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), energy-dispersive spectrometer (EDS), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), and mappings. XRD confirms that the composite materials lattice planes well correspond to the patterns of Li₂CoTi₃O₈, CoTiO₃, and TiO₂, respectively. SEM and TEM exhibits the fabricated composites are one-dimensional nanofibers with the diameter of 250~300 nm and 150~200 nm after annealing, respectively. The electrochemical properties of the materials for LIBs are investigated to indicate that the (LCT) composite nanofibers hold high reversible capacity of 201.68 mAh g⁻¹ after 120 cycles and high rate capability at different current densities.
