Toward the Controlled Synthesis of Nanostructured Si and SiO _x Anodes for Li-Ion Batteries via SiO₂ Magnesiothermic Reduction Reaction.

ABSTRACT: Nanostructured SiOx (0 ≤ x ≤ 2) materials are key for boosting energy density in next-generation Li-ion battery anodes, with the magnesiothermic reduction reaction (MgTR) emerging as a scalable pathway for their production from nanoporous SiO₂. In MgTR, SiO₂ reacts with Mg at moderate temperatures to form Si and MgO, enabling the preservation of nanostructured features. However, the widespread application of MgTR is hindered by the strong influence of reaction parameters on process dynamics, which leads to the uncontrolled formation of multiple byproducts that not only reduce the Si yield but also require the use of hazardous hydrofluoric acid (HF) for their removal, hampering the synthesis of SiO _x due to HF's reactivity with SiO₂.
