| description | Li<sub>4</sub>Ti<sub>5</sub>O<sub>12</sub> (LTO) is an alternative anode material to substitute commercial graphite for lithium-ion batteries due to its superior long cycle life, small volume change (zero strain), good thermal stability, and relatively high power. In this work, iodide-doped LTO is prepared by solid-state reaction method via ball milling method and subsequently calcined at 750 °C for 10 h in air atmosphere. X-ray diffraction (XRD) of iodide-doped LTO reveals the spinel cubic structure without any impurities detected. The 0.2 mol lithium iodide-doped LTO shows enhanced high-rate capability with a specific discharge capacity of 123.31 mAh g<sup>−1</sup> at 15 C. The long cyclic performance of 0.2 mol lithium iodide-doped LTO delivers a specific discharge capacity of 171.19 mAh g<sup>−1</sup> at 1 C with a capacity retention of 99.15% after 100 cycles. It shows that the iodide-doped LTO is a promising strategy for preparing a high electrochemical performance of LTO for the anode of lithium-ion batteries. |
