Abstract

A Si/Ge nanocomposite composed of interconnected Si and Ge nanoparticles is prepared through a one-step solid-state metathesis reaction between Mg2Si and GeO2 for the first time. As an anode, the Si/Ge electrode exhibits a reversible capacity of 2404.7 mA h g−1 at 0.5 A g−1 over 60 cycles and long-term cycling stability with a capacity of 1260 mA h g−1 over 500 cycles even at 5 A g−1.
