Metallothermic Reduction at Low Temperature Synthesis of Ti₄O₇ Powder with Lithium Ion Insertion/Extraction Property

Article Preview

Abstract:

In this work, a thermal reduction process via ultrafine titanium powder as the reducing agent under argon atmosphere is firstly used to prepare Ti₄O₇. Compared with the conventional method, this experiment process reduces the sintering temperature to 850°C. The phase transformation and the morphology of the as-prepared powders are examined by X-Ray diffraction (XRD) and scanning electron microscopy (SEM). Besides, it is found that the Ti₄O₇ powders obtained by titanium thermal reduction method exhibited the crystal structure, distinctly possessing an average particle size around 750 nm. The as-prepared Ti₄O₇ nanoparticles are used as anode active material in lithium battery. The results demonstrate that the anode with Ti₄O₇ calcined at 850°C by titanium thermal reduction method exhibited insertion/extraction lithium ion property.
