Synthesis of Amorphous Fe-Doped SiO₂ Anode Nanomaterial via Sol-Gel Method

Abstract:

Silicon-based anode is one of the most promising anode materials for next generation batteries due to its high theoretical capacity of about 4200 mAh/g. However, the hurdle of using such high capacity anode material is its large volumetric change during lithiation and delithiation causing capacity fading. In this study, in order to circumvent the large volumetric change, nanograined size SiO₂ incorporated with Fe having compositions of Fe_xSi_1-xO₂ (x=0.05, 0.10) have been synthesized using a modified sol-gel processing and fully characterized for its structure, morphology, and thermal properties. From the different characterization results, the samples synthesized at low processing temperatures (400 and 600 °C) suggest an amorphous structure with grain size of about 5 nm and Fe successfully incorporated into the amorphous nanograined SiO₂matrix.
