- Hierarchical entangled Co(OH)2 nanorods (NRs) are anchored on graphene foam (GF) electrodes by usinga facile chemical bath deposition (CBD) method. The porous, conducting, and higher specific area accessoffered by the interconnected 3D graphene framework along with unique Co(OH)2 NRs morphology ofelectrode displays ultrahigh specific capacitance, energy and power density. The Co(OH)2/GF electrodereveals maximum specific capacitance about 1139 F g−1 at 10 A g−1charge-discharge current densityin 1 M KOH aqueous solution. Moreover, Co(OH)2/GF electrode in the symmetric supercapacitor device,reveals a high energy (13.9 Wh kg−1) with power (18 kW kg−1) density. These results promote the poten-tial applicability of Co(OH)2/GF electrode in the supercapacitor field with effective boosting in chargetransfer and storage mechanism.
