Abstract
A method of producing a silicon/carbon composite material which includes the following successive steps: providing a silicon/polymer composite material from silicon particles and a carbonaceous polymer compound, precursor of carbon and able to be cross-linked, performing at least partial cross-linking of the polymer of the silicon/polymer composite material so as to obtain a cross-linked silicon/polymer composite material, the polymer having a cross-linking rate greater than or equal to 50% and, pyrolyzing the cross-linked silicon/polymer composite material until said silicon/carbon composite material is obtained.
