Abstract: Supercapacitive behaviour of a novel functional material, nickel (II) octa [(3,5-biscarboxylate)-phenoxy] phthalocyanine (NiOBCPPc) upon covalent integration with phenylamine functionalized single-walled carbon nanotubes (SWCNT-phenylamine ) is reported for the first time. The supercapacitive behaviour of the hybrid (NiOBCPPc-SWCNT-phenylamine) was investigated using galvanostatic charge–discharge and electrochemical impedance spectroscopy. Using a more reliable galvanostatic charge–discharge method, the NiOBCPPc-SWCNT-phenylamine hybrid exhibited superior geometrical capacitance (~186mFcm-2) compared to either NiOBCPPc (~54mFcm-2) or SWCNT-phenylamine (~74mFcm-2) at a current density of 138µAcm-2. The NiOBCPPc-SWCNT-phenylamine gave excellent stability of over 1000 charge–discharge continuous cycling.
