Mesoporous silica nanoparticles as high performance anode materials for lithium-ion batteries

Abstract

A facile sol–gel/emulsion approach was employed for the fabrication of mesoporous silica nanoparticles with a large BET specific surface area of 1594 m² g⁻¹. The as-prepared SiO₂ electrode delivers a highly stable specific capacity of as large as 1060 mA h g⁻¹ at a current density of 100 mA g⁻¹ after 90 cycles, exhibiting a good cycling stability.
