Abstract
This invention relates to particulate electroactive materials consisting of a plurality of composite particles, wherein the composite particles comprise: (a) a porous carbon framework including micropores and mesopores having a total volume of 0.5 to 1.5 cm3/g; and (b) silicon located at least within the micropores of the porous carbon framework in a defined amount relative to the volume of the micropores and mesopores. At least 20 wt % of the silicon is characterized as surface silicon by thermogravimetric analysis.
