“…The higher CV area and redox peak intensity than other electrodes indicate better capacitance and fast redox kinetics. The electrode exhibits a specific areal capacitance of 4389 mF/cm 2 at a current density of 5 mA/cm 2 and 82.4 % of it is retained due to the hydrophilicity of PANI which makes electrolyte ions accessible to electrode surface . The capacitance is mainly due to the synergistic effect of high surface area and porosity of ZnO@ZIF‐8, electrical conductivity of carbon cloth and pseudo‐capacitance of PANI.…”

“…The electrode exhibits a specific areal capacitance of 4389 mF/cm 2 at a current density of 5 mA/cm 2 and 82.4 % of it is retained due to the hydrophilicity of PANI which makes electrolyte ions accessible to electrode surface. [85] The capacitance is mainly due to the synergistic effect of high surface area and porosity of ZnO@ZIF-8, electrical conductivity of carbon cloth and pseudo-capacitance of PANI. The high conductivity imparted by carbon cloth support results in low equivalent series resistance as seen from Nyquist plots which confirms that it offers low resistance to the diffusion and transport of ions and electrons.…”

Carbon cloths are the important materials composed of woven carbon fibres having the diameters in the range of 5–10 μm. These materials have been investigated for innumerable applications such as supercapacitors (symmetric and asymmetric), batteries, solar cells, and catalysis. They are found to be the best supports as supercapacitive materials by providing high surface area, conductivity and flexibility compared to much widely used substrate materials such as Ni foam and 1D Fe nanowires. High conductivity and surface area of carbon cloths enable ion diffusion and cause decrease in charge transfer resistance, resulting in an increase of specific capacitance of specific electrodes. Several supercapacitive metal oxides, chalcogenides, phosphides, MXenes, carbon nanotubes, graphene, and conductive polymers have been incorporated into carbon cloths to improve their energy storage activity. Further modification of carbon cloth surface via oxidation, doping and by the growth of different nanostructures is also helpful as it increases the electroactive surface area necessary for electrochemical interaction. The present review mainly focuses on the development of flexible supercapacitors using carbon cloth‐based substrate materials. Such flexible supercapacitors can be further utilized for an uninterrupted and steady power supply to wearable and portable electronic devices.

Owing to their tunable conductivity, good processability, environmental friendliness, and unique doping–dedoping characteristics, conducting polymer (CP)‐based flexible supercapacitors have been widely investigated. Inclusion of CPs into flexible substrates has been demonstrated to be an efficient way for fabricating CP‐based flexible supercapacitors. This paper provides a focused review on recent progresses in the research and development of CP‐based flexible supercapacitors. The synthesis and electrochemical performances of CP‐based hydrogels, including the pristine CP hydrogels, hybrid hydrogels, and all in one supercapacitors, are highlighted. The latest progress in the development of flexible supercapacitors based on binary and ternary hybrid films consisting of CP/carbon nanotubes, CP/graphene, or CP/graphene/carbon nanotubes is discussed. Furthermore, a brief summary of the use of CP‐based textiles and fibers for flexible supercapacitors is also presented, along with the current challenges and future perspectives for CP‐based supercapacitors.

In the past decades, pseudocapacitive materials (PCMs) for electrochemical energy storage have drawn enthusiastic attention from researchers, owing to their virtue of larger Faradaic capacitance facilitating enhanced energy densities compared to electric double-layer capacitive materials. To maximize capacitive properties without sacrificing power densities, novel design and fine fabrication of innovative PCMs with rational microstructures become of significant importance. Typically, enormous efforts have been devoted to fabricating 1D nanostructured PCMs for advanced supercapacitors, thanks to their geometrical merits facilitating the ionic/electronic transport. This review mainly focuses on the latest development and progress of 1D nanostructured PCMs for advanced super-capacitors. Firstly, typical pseudocapacitive mechanisms are discussed in detail. Secondly, physicochemical properties and intrinsic merits of 1D nanoscaled electrodes are comprehensively described. Thirdly, representative synthetic methodologies, optimization strategies and involved formation mechanisms for 1D nanodimensional PCMs are surveyed. Besides, the applications of 1D versatile PCMs including 1D conventional nanostructures, nano-arrays, core-shell nano-architectures and secondary superstructures are systematically summarized as competitive electrodes for supercapacitors. Finally, future challenges, prospects and opportunities of 1D nanostructured PCMs for next-generation supercapacitors are further proposed.
