“…It has been proved that the hydrophilic property of electrode materials has a big impact on the electrochemical behavior of supercapacitors ,. The wetting of electrode with water is related to surface morphology and chemical content of the electrode surface . The wettability of flexible films was investigated when distilled water was used as the probing liquid for measuring the contact angles.…”

A facile and low-cost strategy has been developed to prepare a highly porous polyaniline/carbon nanotube/polyvinyl chloride film (PANI-CNTs-PVC) as an electrode for flexible supercapacitors with the improved performance. The flexible porous film was fabricated via introducing Zn nanopowder into the composition of PANI-CNTs-PVC film and then leaching of Zn from the obtained film in an acidic solution. A maximum areal capacitance of 298 mF cm À2 with 86.5 % retention after 5000 cycles at a current density of 0.6 mA cm À2 is achieved for the porous flexible PANI-CNTs-PVC film. The capacity is considerably larger than that of the non-porous flexible PANI-CNTs-PVC film prepared without Zn introduction process (90 mF cm À2 with 87 % retention after 5000 cycles). The excellent electrochemical performance of the porous PANI-CNTs-PVC film compared to non-porous PANI-CNTs-PVC film is due to the porous 3D network structure and its high hydrophilic property which help to transport electrolyte to the inner region of the composite and facilitate the charge-transfer between the film and electrolyte. Furthermore, an all-solid-state symmetric supercapacitor fabricated from two porous flexible PANI-CNTs-PVC films with solid-state PVA/H 2 SO 4 gel as electrolyte displayed superior flexibility and high electrochemical activity.

“…Kumbhar et al developed Sm 2 S 3 thin film that used chemical synthesis to achieve the maximum specific capacitance of 213 F g À 1 @5 mVs À 1 scan rate. [30] The binary composite of GO/ Sm 2 S 3 gives a remarkable specific capacitance of 360 F g À 1 at the same scan rate. [31] Many reports provide evidence of how composite materials can enhance the overall electrochemical performance than pristine ones.…”

“…Moreover, the current depends nonlinearly on scan rate, i. e., scan rate 0.5 . [25] The materials such as different transition metal oxides/ hydroxides: MnO 2 , RuO 2 , V 2 O 5 , etc., [26][27][28][29][30] were used for the supercapacitor application during past few years. These materials enhance electrochemical performance through reversible redox reactions.…”

In this study, we synthesized a binder‐free composite electrode based on Sr(OH)2/MnO2 material. The active electrode was prepared using the layer‐by‐layer (LBL) technique. The surface architecture of the sample was examined through scanning electron microscopy (SEM) and high‐resolution scanning electron microscopy (FE‐SEM). Further, the microstructural information of the electrode was revealed via transmission electron microscopy (TEM). The composite confirmation was ensured through X‐ray diffraction (XRD), Fourier‐transform infrared spectroscopy (FTIR), and energy‐dispersive X‐ray spectroscopy (EDX) spectra with mapping analysis. The electrode exhibited the maximum specific capacitance of 554.7 F g−1 at 5 mVs−1 in the 6 M KOH electrolyte. The electrode maintained ~65 % capacitance retention after 10,000 galvanostatic charge‐discharge (GCD) cycles. Furthermore, the assembled symmetric supercapacitor device exhibited the highest specific capacitance value of 124.7 F g−1 @ 5 mVs−1 within a potential span of 1.2 V. This device demonstrated the capability to illuminate light‐emitting diodes (LEDs) of different colors. The energy and power densities of the device were calculated as 26.66 Wh kg−1 and 9884.54 W kg−1 respectively. The stability performance of the device was ~57 % after 10,000 GCD cycles. These findings strongly suggest that the material and the device represent promising options for future energy storage applications.
