摘要: Abstract The commercial Li4Ti5O12 (LTO) is successfully modified by AlF3 via a low temperature process. After being calcined at 400 °C for 5 h, reacts with LTO to form composite material which mainly consists of Al3+ and F− co-doped small amounts anatase TiO2. demonstrates ultrahigh rate capability comparing the pristine LTO. Since amount byproduct TiO2 relatively small, electrodes retain main voltage characteristics minor feature similar those doped anodes deliver slightly higher discharge capacity maintain excellent long-term cycling stability when compared anode. Therefore, synthesized an anode stable ultra-high power lithium-ion batteries.
