Abstract

A new strategy is proposed to synthesize a Si−Ge alloy nanomaterial for a Li-ion battery anode. Magnesiothermic reduction of the SiO₂−GeO₂ composite parent material could provide a nanostructured Si−Ge alloy material with unique canyon-like surface porosity. The nanostructure of Si−Ge alloys could be intentionally controlled and the resulting canyon-like porous Si−Ge nanoparticle could be successfully utilized as an anode material, achieving satisfactory cell performance. The proposed synthetic approach can potentially scale-up the production of Si−Ge alloy nanomaterial.
