Abstract

Methods of forming a composite material film can include providing a mixture comprising a precursor and silane-treated silicon particles. The methods can also include pyrolysing the mixture to convert the precursor into one or more carbon phases to form the composite material film with the silicon particles distributed throughout the composite material film.
