Abstract

Functionalized 3D nanographenes with controlled electronic properties have been synthesized through a multistep organic synthesis method and are further used as promising anode materials for lithium-ion batteries, exhibiting a much increased capacity (up to 950 mAh g^-1 ), three times higher than that of the graphite anode (372 mAh g^-1 ).

Keywords: anode materials; bottom-up synthesis; graphene; lithium-ion batteries.
