Synthesis and Electrochemical Properties of Lithium Titanate Anode Materials Powders by Solid State Reaction of Li and Spherical TiO₂ Powders

Abstract:

Li₄Ti₅O₁₂ powders were synthesized by solid state reaction of Li₂CO₃ and spherical composite powders of carbon and TiO₂ (denoted as C/TiO₂). C/TiO₂ powders were synthesized by spray pyrolysis of using lactic acid aqueous solution. The particle characteristics of Li₄Ti₅O₁₂ powders were determined by SEM, XRD and DTA-TG. DTA-TG showed that the carbon content was around 8 wt% in Li₄Ti₅O₁₂ powders. XRD revealed that the spinel structure (Fd3m) was obtained by heating at 750 °C under N₂ atmosphere. The first rechargeable capacity of Li₄Ti₅O₁₂ anode was about 160 mAh/g at 1 C. That of Li₄Ti₅O₁₂ anode decreased to 90 mAh/g at 20 C. The rechargeable capacity of Li₄Ti₅O₁₂ anode decreased with increasing the rechargeable rate, but 81% of initial discharge capacity of Li₄Ti₅O₁₂ anode was retained after 200 cycles at 1C
