Nanostructured silicon has attracted a great deal of attention as an excellent anode material for Li ion batteries (LIBs). However, the use of Si nanomaterials in LIBs is severely hindered by their preparative methods owing to the high cost, low yield, and harsh synthetic conditions. Herein, we report a new method for the synthesis of uniform Si nanocrystals based on the magnesiothermic reducti...

The silicon nanostructure is a promising candidate for an anode of Li-ion batteries due to its high theoretical capacity. In this work, we have demonstrated the scalable synthesis of Si nanosheets from natural sand by magnesiothermic reduction, and suggested a new formation mechanism for Si nanosheets. In the suggested mechanism, an Mg₂Si intermediate phase was formed at an early stage of the r...

The comprehensive utilization of Si-rich biomass is restrained by macromolecular lignin and a large amount ash. In this study, rice husks (RHs) are treated as representative alkali extraction acid precipitation, the obtained lignin-SiO2 composite modified carbonazation, ball milling, magnesiothermic reduction additives. Through these processes, Si/C with excellent electrochemical properties per...

This study presents the magnesiothermic reduction of silica into silicon. process occurs at a lower reaction temperature than its carbothermal counterpart. Furthermore, was extracted from sugarcane bagasse ash via thermo-chemical treatment method using, for first time, L-cysteine chloride monohydrate and used as precursor in production silicon using reduction. The as-synthesized nanocrystalline...
