Graphene-nanosheet clusters with flower-like hierarchical structure (f-GNSCs) were facilely fabricated by an electrochemical method with the assistance of copper particles. Such unique 3D macroporous graphene (GE) structure possesses remarkable electrochemical capacitance (up to 347.1 F gā1), good rate capability and cycle stability.
