Solvothermal Synthsis of Nano-Sized Li₄Ti₅O₁₂ Particles as Anode Material for Lithium Ion Batteries

Abstract:

We synthesized nano-Li₄Ti5O₁₂ particles by solvothermal method. The as-prepared materials were characterized by XRD, SEM, TEM and electrochemical measurements. The Li₄Ti5O₁₂Li4Ti5O12 showed excellent rate capability and cycle ability. The as-preparedLi₄Ti5O₁₂ Li4Ti5O12 electrode exhibited highly initial discharge capacity 176 mAh/g at 0.1 C rate up to, which was slightly higher than its theoretical capacity (175 mAh/g). By increasing the C-rate, the cell showed 152, 143, 138 and 135 mAh/g at 0.5, 1, 1.5 and 2 C, respectively.
