Low cost and abundant natural ilmenite (FeTiO3) is used as raw materials for preparing TiO2–carbon nanocomposites. A new method combining several traditional techniques (ball milling, high-temperature annealing and chemical leaching) is proposed in this paper. The resulting composite is a spherical material, consisting of nanosized TiO2particles (with a size range of 5–80 nm) homogeneously distributed in carbon (amorphous) matrix. Its electrochemical performance is evaluated by using coin-type cells versus metallic lithium in an enlarged potential window of 0.01–3.0 V. A high specific charge capacity of 722 mA h g−1is obtained at a current density of 33.6 mA g−1. Moreover, the TiO2–carbon nanocomposite exhibits excellent rate capability, even at a high current density of 10.8 A g−1, the specific charge capacity is 41 mA h g−1.
