Preparation and Electrochemical Performances of Li₄Ti₅O₁₂ as Anode Material

Abstract:

Spinel Li4Ti5O12 was prepared by a solution method. The structure and morphology of the samples were characterized by X-ray diffraction, scanning electron microscopy. The electrochemical performance was investigated by initial charge-discharge at different rate. The results revealed that the crystallinity of Li₄Ti₅O₁₂ was well, the Li₄Ti₅O₁₂ prepared by solution method had a relatively smaller particle size and homogeneous morphology. It delivered a discharge capacity 178.59 mAh•g⁻¹ for the Li₄Ti₅O₁₂ at the 0.2C discharge to 1V. The reversible capacity 141.98mAh•g⁻¹ could be achieved at the 5C . Li₄Ti₅O₁₂ prepared by a solution method showed good rate performance.
