Effect of Synthesis Temperature on Structure and Electrochemical Properties of Nano-Sized Li₄Ti₅O₁₂ by Self-Combustion Method

Abstract:

The spinel-type Li₄Ti₅O₁₂ cathode materials were synthesized by a self-combustion method. The effects of synthesis temperature on the structural and electrochemical properties of the Li₄Ti₅O₁₂ were investigated. The prepared samples were characterized by X-ray diffraction (XRD), SEM, TEM and electrochemical analysis. The results revealed that pure phase and well-crystallized Li₄Ti₅O₁₂ with nano-sized could be synthesized at a calcination temperature of 750°C. The sample prepared under the condition had the highest initial discharge capacity of 164 mAh/g and shown good capacity rentention during 50 cycles between 1.0-2.5V at 0.1C.
