ELECTRODE MATERIAL COMPRISING GRAPHENE COMPOSITE MATERIALS IN A GRAPHITE NETWORK FORMED FROM RECONSTITUTED GRAPHENE SHEETS

摘要

A durable electrode material suitable for use in Li ion batteries is provided. The material is comprised of a continuous network of graphite regions integrated with, and in good electrical contact with a composite comprising graphene sheets and an electrically active material, such as silicon, wherein the electrically active material is dispersed between, and supported by, the graphene sheets.
