From: Ultrahigh capacitive performance from both Co(OH)2/graphene electrode and K3Fe(CN)6 electrolyte
Cyclic voltammograms at a scan rate of 25 mVs−1 (a), Galvanostatic charge-discharge curves at a current density of 16 Ag−1 (b), specific capacitance and high-rate discharge ability vs. different K3Fe(CN)6 concentrations (c) for the system of Co(OH)2/GNS electrode in 1 M KOH containing different concentrations of K3Fe(CN)6 mixed solution.
