In this study, electrospun polyacrylonitrile-(5,10,15,20-tetra(4-tert-butylphenyl))-porphyrin nanofibers (PAN-Por NFs) were carbonized to obtain PAN-Por NF/carbon-felt electrodes (PP2C/CFE), which then investigated for their performance as battery-type hybrid supercapacitor (SC) electrodes. To the best of our knowledge, doping a SC electrode with (5,10,15,20-tetra(4-tert-butylphenyl)porphyrin has not been previously investigated. Subsequently, series physicochemical analyses conducted, including scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, Fourier-transform infrared and polarization optical microscopy. Electrochemical performed using cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), electrochemical impedance spectroscopy. The PP2C/CFE exhibited characteristics in CV GCD tests. From data, maximum specific capacitance was calculated be 220 F g−1 at 0.5 mV s−1. At current density A g−1, 177 capacity 284 mAh from curve. highest coulombic efficiency, 110.60%, observed 3 g−1. 98.3 Wh kg−1, power 348.6 W kg−1. cycle-stability test, 50 cycles 3.5 resulting an 88% increase value. This study demonstrates, first time, that doped/carbonized Por is promising improvable electrode.
