A lotus‐root‐like three‐dimensional mesoporous silicon is successfully prepared by a magnesiothermic reduction method using SBA‐15 silica as both template and silicon precursor. After carbon coating via a chemical vapor deposition process, this anode material shows high reversible capacity of ∼1900 mAh g −1 and excellent rate performance even up to 15C.
