Abstract:
1. A process of forming an electrochemically active material, the process comprising: preparing a solution comprising: polymerizing the monomer to form a polymer-silicon precursor matrix; and pyrolyzing the polymer-silicon precursor matrix to form an electrochemically active carbon-coated silicon material which is a compound of formula SiO wherein: the monomer or mixture of monomers comprises phenol, urea, benzene-1,3-diol, benzene-1,2-diol, benzene-1,4-diol, methylene phenyl diisocyanates, styrene, methyl methacrylate, vinyl chloride, vinyl fluoride, toluene diisocyanate, melamine, or formaldehyde.
