Abstract

Novel Si/SiOx/SiO2 nanocomposites were prepared via a facile and scalable wet synthesis. The amorphous structure, nanoscale particle size, and composition of the Si/SiOx/SiO2 material were characterized and its electrochemical performance as an anode for Li-ion batteries was evaluated. The material shows a stable cycling capacity of ∼600 mA h g-1 over 350 cycles with high coulombic efficiency of >99%.
