摘要：

Magnesium thermal reduction of the silica aggregation following with HF etching is used to obtain mesoporous nano-Silicon. The product shows an 1844 mAh g(-1) discharge capacity in the first cycle with 400 mA g(-1) current density and it still delivers a 1444 mAh g(-1) capacity after 100 cycles. Additionally, it presents a good rate capability. The mesoporous morphology and the ultra-fine particle are the reasons of the good electrochemical property. (C) 2014 Elsevier B.V.
