Title: Silicon-carbonaceous encapsulated materials

Abstract

A process includes preparing a solution including a silicon precursor or mixture of silicon precursors and a monomer or mixture of monomers; 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.
