  4. Abstract:
  5. The authors regret We have found, there is a problem with the image orders in the last version of the article that is being published online. In the accessible version, the caption of the images are exactly in the true orders, but the images are shifted up and they are not shown in their exact positions. This Corrigendumm is being released for revision of the image orders, like what they were in the accepted version of the manuscript. The materials are shown in the following pages. The authors would like to apologise for any inconvenience caused. [Formula presented] Scheme 1. Binder-free fabrications of the PPOGrCNT on nickel foam (Ni/PPOGrCNT electrode). [Formula presented] Fig. 1. (a) FT-IR, (b) Raman and (c) XRD spectra of the active materials including GO, CNTOx, RGO, PPOGr and PPOGrCNT powders. [Formula presented] Fig. 2. TEM and SEM images of PPOGrCNT composite together with GO, RGO, CNTOx, GrCNT, and PPOGr powders. [Formula presented] Fig. 3. (a) Sorption isotherms; (b) BJH pore size distribution of PPOGrCNT and GrCNT; (c) Thermogravimetric analysis and (d) the respective differential plots for PPOGrCNT compared to GO. [Formula presented] Fig. 4. (a) XPS of PPOGrCNT powder after hydrolysis compared to the spectrum of GO and RGO that prepared at 800 °C, (b–e) deconvoluted spectra of P, C, N and O atoms for PPOGrCNT sample. [Formula presented] Fig. 5. (a) CV plots (at 10 mV s−1), and (b) Nyquist plots of Ni/PPOGrCNT compared to other electrodes (in frequency range of 105–10−2 Hz). (c) CV curves of Ni/PPOGrCNT at different scan rates of 5–100 mV s−1. (d) Specific capacitance relating to scan rate based on the CV results. Potentials represented vs. (Ag/AgCl) and electrolyte was 1 M NaCl solution. [Formula presented] Fig. 6. (a) GCD curves over the potential range of −1 to 0 V at current densities of 0.7–3.4 (A g−1) and (b) Specific capacitances vs. current density for Ni/PPOGrCNT. Stability test of Ni/PPOGrCNT electrode via GCD technique at loading current of 7.5 mA cm−2 (or 2.2 (A g−1) for 3000 cycles (36 h): (c) plots of selected cycles, (d) specific capacitances. Potentials represented vs. Ag/AgCl in a three electrode system in 1 M NaCl solution. [Formula presented] Fig. 7. The life cycle stability test for Ni/PPOGrCNT electrodes conducted via symmetric two-electrode geometry (for 300 ads/des cycles in 13 days). The geometric surface area of electrodes were 3 × 2 cm2 that were immersed into the batch cell containing 50 mL of 500 ppm NaCl solution; (a) diagram of current (mA) vs. applied voltage (mV) for the selected cycles; (b) plot of the NaCl concentration (ppm) vs. time regarding the applied potential during the cycles of (15th–35th). [Formula presented] Fig. 8. The SEM images in 1 KX magnifications for the Ni/Gr, Ni/PPOGr, Ni/PPOGrCNT, and Ni/PPOGrCNT-PVDF electrodes at the beginning (top) and after the symmetric CDI life cycle stability tests in a batch cell containing 50 mL of 500 ppm NaCl solution (down); Ni/Gr after 200 cycles (9 days), Ni/PPOGr and Ni/PPOGrCNT after 300 cycles (13 days); and Ni/PPOGrCNT-PVDF after 45 cycles (2 days). © 2021 Elsevier B.V
