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 0.4 to 0.75 cm/g, wherein the micropore volume fraction is in the range of 0.5 to 0.85 based on the total volume of micropores and mesopores; 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.
