Abstract

Described herein is a nanostructured silicon carbonaceous composite material and methods for producing the same. The methods include formation of a metal organic framework/silica (MOF/SiO.sub.2) intermediate material and conversion of the MOF/SiO.sub.2 intermediate material to the nanostructured silicon carbonaceous composite material. Relatively inexpensive and/or recycled materials can be used as precursors in manufacturing the nanostructured silicon carbon composition material, which can be used in various applications, including as silicon anode material in a lithium-ion battery.
