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.
