Silo Meoto

The invention provides methods for providing composite particles with a carbon coating and the resulting core-shell particulate material. The process comprises subjecting a plurality of precursor composite particles to a heat treatment in contact with a pyrolytic carbon precursor such that an outer shell of a pyrolytic conductive carbon material is formed on the precursor composite particles, wherein the heat treatment is carried out at a temperature of no more than 700° C.

Silicon-carbon composite materials and methods

This invention relates to particulate electroactive materials consisting of a plurality of composite particles, wherein the composite particles comprise: (a) a porous conductive particle framework including micropores and/or mesopores having a total volume of at least 0.4 to 2.2 cm/g; (b) an electroactive material disposed within the porous conductive particle framework; and (c) a lithium-ion permeable filler penetrating the pores of the porous conductive particle framework and disposed intermediate the nanoscale silicon domains and the exterior of the composite particles.
