Influence of Sintered Temperature on Spinel LiMg_0.06Mn_1.94O₄ Synthesized by Flameless Liquid-Phase Combustion Method

Abstract:

The LiMg_0.06Mn_1.94O₄ calcined at 500 °C for 3 hours then sintered at 600 °C, 700 °C and 800 °C for 3 hours by flameless liquid-phase combustion synthesis are prepared. Particle properties were characterized by X-ray diffraction, scanning electron microscopy and Fourier transform infrared spectroscopy. Besides, galvanostatic tests and electrochemical impedance spectroscopy were performed to investigate the cycling performance. Particle properties analyses showed that LiMg_0.06Mn_1.94O₄ sintered at 600 °C has a single phase and the average grain size is about 80-200 nm with a little agglomeration, it also displays the highest initial capacity of 114.2 mAh/g and still remains 82.7% after 40 cycles. Results showed that sintered temperature by nitric acid assisted liquid-phase combustion method should be 600 °C.
