Abstract

Abstract : Graphene-ordered mesoporous carbon hybrids exhibited advanced specific capacity, high energy density and power density, and long cycle life. Abstract : Ordered mesoporous carbon/graphene hybrids (OMCGs) with large specific surface areas (1795 m 2 g −1 ) have been firstly synthesized by the direct self-assembly of soluble phenolic resin, an F127 triblock copolymer and tetraethyl orthosilicate (TEOS) on the surface of graphene oxide. The resulting OMCG electrode shows an advanced specific capacity of 330 F g −1, a high energy density of 38.1–32.3 W h kg −1 and a power density of 6.1–61.1 kW kg −1, and long cycle life.
