摘      要：Hierarchical Ni CoO/PANI/CNTs hybrid composites were designed and fabricated having a layer of Ni CoOon the surface of PANI encapsulated CNTs with different morphologies. Physicochemical attributes of the synthesized composites were examined by FTIR, UV–visible and X-ray diffraction（XRD）techniques. Morphological aspects were evaluated by field-emission scanning microscopy（FESEM）,electron diffraction spectroscopy（EDS）, high resolution transmission electron microscopy（HRTEM） and selected area electron diffraction（SAED） studies. Electrochemical measurements revealed an improved specific capacitance of 2250 F/g at a scan rate of 5 m V/s and 2000 F/g at a current density of 1 A/g with good rate capability using a three-electrode system. These enhanced features are achieved from the well designed nanostructure and the synergistic contributions of individual components in the electrode material.
