Uniform and stable micro-sized SnO2 hollow spheres are prepared by templating against polystyrene microspheres. After being coated with a thin layer of amorphous carbon, the as-obtained SnO2@carbon hollow microspheres are shown to exhibit improved lithium storage properties, delivering a reversible capacity of 570 mA h g−1 after 50 cycles at a high current density of 400 mA g−1.
