摘要：

Carbon-encapsulated Si nanoparticles were formed by carbonizing a resorcinol-formaldehyde gel polymerized in the presence of phenol-functionalized Si particles. These encapsulated Si showed higher reversible charge capacity and Coulombic efficiency for use as lithium ion battery anode than samples prepared with Si nanoparticles without phenol functionalization.
