Carbon nanospheres grown on graphene as anodes for Li-ion batteries

Abstract

An electrode composed of graphene/carbon nanospheres is synthesized via in situ polymerization and carbonization, for Li-ion batteries. Carbon nanospheres derived from carbonized polypyrrole are grown on the surface of graphene and assembled into a flake-like structure. The synergistic effect between carbon and graphene improves the capacity and rate capability of the electrode.
