Synthesis of Li4Ti5O12 Anode Material for Lithium-Ion Batteries
Li4Ti5O12 spinel-type anode materials were synthesized by high-energy ball milling and solid-state method using TiO2 (Anatase) and Li2CO3 as starting materials. The powders were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), thermo-gravimetric (TG)/differential scanning calorimetric (DSC). The results showed that Li4Ti5O12 in a single phase can be fabricated above 750 °C for 3h when the mixture powders were high-energy ball milled at 500r/m for 30min. The grain size was 0.3-0.5 m and particle size distribution was narrow.
