NOVEL CARBONIZED POLYANILINE-GRAFTED SILICON NANOPARTICLES ENCAPSULATED IN GRAPHENE SHEETS FOR LI-ION BATTERY ANODES

摘要

A method for producing a graphene-composite material, including removing any oxide layer from each of a plurality of silicon nanoparticles, forming a polyaniline layer over each clean silicon nanoparticle, binding a graphene oxide sheet to the polyaniline layer of each particle, and carbonizing the polyaniline to yield a plurality of composite particles. Each composite particle has a graphene outer layer substantially encapsulating a silicon inner core.
