Using amorphous TiO2 microspheres as precursors, we obtain mesoporous TiO2–Sn@C core–shell microspheres. Sn is encapsulated into a TiO2 matrix, and carbon is coated outside. This intriguing architecture can effectively buffer volume change and structural stress, thus contributing to excellent long-term cycling stability and superior high-rate cyclability.
