Abstract
Carbonaceous insertion compounds and methods for preparation are described wherein the compounds comprise silicon and oxygen and are characterized by x-ray diffraction patterns that resemble that of amorphous silicon dioxide. The compounds can exhibit a large reversible capacity for lithium and can be prepared by simple pyrolysis of suitable polymer/s containing silicon, oxygen and carbon at an appropriate temperature. These insertion compounds may be suitable for use as high capacity anodes in lithium ion batteries.
